Annotation. The impossibility of intuitive understanding of the most diverse spectrum of quantum phenomena reduces to the need to use all physical and mathematical methods before all empirical and experimental actions. One of the most popular and important in this vein is a linear partial differential equation describing the change in space and time of the pure state, given by the wave function, in Hamiltonian quantum systems for photonic phenomena expressed in a stationary state.
Keywords: Schrodinger equation, stationary state, spectral problems, quantization, differential equation, physical and mathematical calculation and modeling.
Аннотация. Невозможность интуитивного понимания самого различного спектра квантовых явлений сводит к необходимости использования перед всеми эмпирическими и экспериментальными действиями всех физико-математических методов. Одним из самым популярным и важных в данном ключе является линейное дифференциальное уравнение в частных производных, описывающее изменение в пространстве и во времени чистого состояния, задаваемое волновой функцией, в гамильтоновых квантовых системах для фотонных явлений выражаемое в стационарном состоянии.
Ключевые слова: уравнение Шрёдингера, стационарное состояние, спектральные задачи, квантование, дифференциальное уравнение, физико-математическое вычисление и моделирование.
Before presenting the question itself, it is worth noting the representation of the one-dimensional stationary Schrodinger equation itself, which is a linear ordinary differential equation of the second order (1), which is also used to solve problems of the spectral plan in wave modeling of photonic phenomena.
In order to solve such an approach, it is necessary to introduce boundary conditions (2), depending on the formulation of which it is possible to determine a general description of the situation and at the same time pay attention to the statement of indicators (3).
Of course, one could try to determine a general solution, but, unfortunately, this is simply impossible and it is necessary to introduce certain boundary conditions that are reduced from certain conditions. A striking example of such states is the solution for a free particle, which is essentially a plane wave. And if we take the potential equation for a free particle, including when taking the corpuscular form of photons, we can get equation (4).
One of the partial solutions is the function (5), derived through a direct solution of a second-order differential equation.
In (4), the constant E can take almost all values above zero, it is from here that we can conclude that the values belong to a continuous spectrum. Moreover, to determine its boundaries, it is necessary to use the integral equation (6), from which the resulting constant C from (5) is obtained.
Hence the value (7) is obtained.
And finally, by substitution, it is possible to obtain a solution of equation (4), for the case of a free particle, which, including, in wave calculus, is a superposition of plane waves (9).
But if this was only one of the special cases, then it is worth considering the case of being in a one-dimensional potential pit with infinitely high walls. After all, if you pay attention to the representations of this question, then it may well be a reducible case in the face of the entry of a photon into a particular atom, provided it approaches the electron shells, the exit from which can play the role of infinitely high walls of a potential well. Also, another larger-scale macro example is the approach of photon radiation to a black hole. For such cases and intervals, the Schrodinger equation coincides with the representation according to (4), from where the boundary conditions for the wave function, previously designated algebraically (2), are represented as (10—11).
The solution, as it was possible to draw attention from other particular solutions, can be reduced to the form (12).
But if we now introduce boundary forms for this type, we can come to a solution of the energy index as (13).
Finally, now it remains only to introduce its own functions, along with the general normalization, and obtain the resulting solution (14).
Thus, some of the partial solutions of the linear Schrodinger equation were considered, each of which can be interpreted in the face of a solution of one kind or another, the number of which can be huge.

Introduction
After all, if you pay attention, during the passage of a certain nuclear reaction, it is necessary to analyze it, and it is the new method of general analysis of a nuclear reaction introduced by Aliyev I. H. that became the basis for demonstrating this type of phenomena, in which the reaction itself is initially described, then its parameters, including output (1), threshold (2), kinetic incoming and outgoing energies (3—4). Next, it is worth referring to the fact that due to the correct selection of the energy close to the Coulomb barrier (5) of the incoming light charged particle, the nuclear effective cross section (6), depending on the de Broglie wave (7), increases sharply, which subsequently leads to an increase in the total beam current (8) that has entered the interaction.
Thus, it can be noted that such a system allows for single or single-multistage reactions. However, in a more modified variation of the setup for such reactions, partly described in a subsequent monograph and textbook devoted to the physics of charged particle accelerators, it was noted that it was possible to conduct several at once, namely, the 6 main resonant nuclear reactions studied at that time using an electromagnet.
In this case, the direction of the beam into each of the reaction compartments creates a pulse transition and leads to the need to create a multi-stage alternating and at the same time strictly discrete magnetic field on the part of the electromagnet, which is already quite an interesting task at this stage. But what is even more noteworthy is the fact of a further sharp increase in the currents of the incoming beam.
The central part
And to control the increased beam, it is necessary to study the nature of the electromagnetic field. The electric field is subject to its measurement due to such a concept as intensity (10), which is characterized by the effect on the fields of a certain charge at a certain distance on the probe charge due to the Coulomb force (9).
The magnetic field has the same ability to calculate, for it this value is called magnetic induction, measured in units – Tesla, named after the great and most brilliant Serbian scientist of his time Nikola Tesla. Since the cause of the magnetic field was previously explained, its first definition is calculated through Maxwell’s equations and their consequences (11—14), which have been discussed in more detail several times.
In addition, if certain exceptions are made due to the property of the action of the magnetic field, in particular, and in statics, then the laws for them will be similar to Coulomb’s laws (15—16), and also in a certain field will be a consequence of the field geometry condition, which is initially assumed by the theorem of Mr. Andre Marie Ampere on the circulation of the magnetic field (17).
However, all these parameters were given only for a general view, but if we turn to specific examples, then first of all it is worth giving a definition of the magnetic induction vector of a straight wire with a known current and a known distance from it is determined by (19).
It is important to note that in order to determine the magnetic induction vector, it is necessary to determine the magnetic permeability of the medium – this is the parameter demonstrating the ability of a material to conduct a magnetic field. Practically the same can be said about such an object as a solenoid – a real electromagnet consisting of a spiral wire and a core. And this small superficial description of the elements of electromagnetism leads to a description of their action on charges.
Where thus, if a free charge enters a magnetic field, then it falls under the influence of a magnetic induction force under the action of a certain Lorentz force (20), under the action of which, taking into account the created centrifugal force (21), the charge begins its rotation with a radius (22).
Moreover, there is also a relativistic form of writing the same formula (23—24).
But these charges, when rotating, again create an alternating electric field, which creates an alternating magnetic field – a parasitic one, and it, in turn, is a new electric one. That is, in this case, the situation with the electromagnetic repeats itself, which requires more detailed consideration.
When one charge enters a magnetic field, a magnetic field acts, but when most of the charges in the conductor begin to fall into such a specific field, the Ampere force (25—27) already acts, which symbolizes the force vector formed by all the conductors in the magnetic field.
As a result, you can get a similar picture of the general description of phenomena.
Conclusion
As a result of this general analysis, it can be said that the application and development of electromagnetism can lead to the improvement of a wide variety of fields of science, even the newest ones, both theoretically and practically. And moreover, each of these innovations improves all these ideas more and more!
