Именно так на данный момент выглядит проект первого в мире ускорителя резонансного типа ЛЦУ-ЭПД-20. А после проведения всего проекта «Электрон» можно достичь осуществления грандиозной работы, которая открывает новые возможности, делает целое государство полностью энергетически независимым, потому что этих 17,56 ГВт*ч электрической энергии более чем достаточно для обеспечения всей Республики Узбекистан на 174,4%, благодаря чему может появиться новая отрасль инфраструктуры являющаяся направлением энергетического экспорта со стороны государства, что также приведёт к улучшению и развитию государственной экономики и не только в промышленном смысле, но также и в самом настоящем научном!
В. English version
1. General concepts of nuclear reactions
By itself, a nuclear reaction is the process of interaction of an atomic nucleus with another nucleus or elementary particle, which may be accompanied by a change in the structure, structure, composition of the nucleus, the formation of new nuclei or elementary particles and the introduction of further changes. Also, the consequence of a nuclear reaction can be its fission, the descent of both elementary particles and massless protons. At the same time, due to the action of several other laws, under which mass can actively be converted into energy and vice versa, the kinetic energy of the resulting particles may well not be equal to the sum of the original ones.
Such nuclear reactions are exo-energetic or energy-releasing. The first nuclear reaction was carried out by Ernest Rutherford in 1917, when alpha particles bombarded the nuclei of nitrogen atoms. It was completely fixed due to the appearance of secondary ionizing particles, whose mileage in the gas was greater than the mileage of alpha particles, after which they were identified as protons. The process was later photographed.
By the way, about this, it is important to say that a Wilson camera is used to photograph nuclear reactions. Speaking about the mechanisms of interaction, we can distinguish two types of such interaction, namely:
1. Reaction with the formation of a composite nucleus, this process consists of two stages, while the incoming particle combines with the bombarded nucleus itself, forming a common core, which later decays. Such a nuclear reaction proceeds at low energies, up to 10 MeV;
2. Direct nuclear reactions that take place immediately, in nuclear time, which is the smallest fractions of a second and are calculated based on other factors, one of which is the time of crossing the nucleus by a particle. Basically, this type of reaction is expressed only at very high energies of the bombarding particles.
If the original nuclei are preserved after the nuclear reaction itself, no new particles are also born, then the reaction is considered elastic scattering in the field of nuclear forces, without any internal interaction. Such a reaction is accompanied only by the transfer of kinetic energy and momentum of one incoming particle to the target nucleus, being called potential scattering and fully obeying the laws of conservation of momentum in this case.
The reaction mechanisms were mentioned earlier, but it is worth dwelling on them in more detail. The first reaction, namely the mechanism of the composite nucleus, was first developed and proposed by Niels Bohr in 1936 together with the famous theory of the droplet model. This theory even today underlies the great ideas about all nuclear reactions.
If we follow this theory, then, as described, the nuclear reaction follows in two stages, while the entire process from collision, formation of a composite nucleus and its decay takes within 10-23-10-21 seconds. And it is important to note that whatever the composite nucleus is, it is always excited due to the excess energy that is introduced by the particle in the face of the binding energy of nucleons in the composite nucleus and part of the kinetic energy of the composite nucleus, which is equal to the sum of the kinetic energy of the target nucleus with a certain large mass number and the incident particle in the system of the so-called the center of inertia.
