If in 1971 212 out of 342 teachers were engaged in research activities, already in 1975 this figure reached 286 people. For comparison, in the same year 1971, 34.2% of the entire academic and professorial staff of FerGPI, and in 1975 – 37.2%, in 1980 38% had academic degrees and titles. From 1972 to 1980, the scientists of the Institute published 70 monographs, textbooks, manuals, developments, 10 collections of scientific papers, 1,500 scientific and popular scientific articles, and also received 20 copyright certificates. In 1972-1978, 6 doctors and 57 candidates of sciences were preparing for defense at the Institute. In 1981-1985, the number of scientific directions became even greater. At that time, the scientists of the Institute published 14 monographs, 5 textbooks and teaching aids, 10 collections of scientific publications, 1100 scientific articles, and also received 7 copyright certificates.

In 1981-1985, research work was carried out on the island of 5 million 723 thousand agricultural contracts.

As rector, Bannob Otakulovich paid great attention to the development of sports and physical culture among students. He trained several champions and prize-winners of Asia and the world. In 1981, the military department was opened. Under his direct supervision, several international and republican scientific and theoretical conferences, seminars and colloquiums were organized at the Institute in various scientific fields. The construction of the Faculty of Medicine, and now the Faculty of Foreign Languages, which was also equipped with all the necessary equipment, was completed.

In the 1973-1974 competitions between republican pedagogical higher educational institutions in the direction of improving the financial and social condition of students, working staff and academic staff. In 1976, a 100-bed preventive wellness center was opened at the Institute. The merits of Bannob Otakulovich in the construction of faculty buildings for recreation areas to improve the functionality of a 120-seat summer health camp for students, workers and academic staff in the Yerdan village in the Ferghana region were simply titanically huge.

Headed by Bannob Otakulovich, economic agreements were drawn up with scientific and analytical institutes in Moscow, Novosibirsk and other cities. A research laboratory and a design bureau were established at the Institute, with more than 20 specialists involved as personnel. This scientific laboratory, together with the world-famous Central Aerodynamic Institute named after Tupolev and Zhukovsky, implemented the terms of agreements worth more than 7.5 million soums.

In 1977, Bannob Otakulovich and his students E. Abdullaev, E. Bilyalov, A. Afuzov became laureates of the Abu Rayhan Beruni State Prize for their scientific work on the topic "Development of semiconductor film tensoresistors and their introduction into the national economy".

In 1979, Bannob Otakulovich defended his doctoral dissertation at the Vilnius State University on the topic "Barrier effects in semiconductors". And for outstanding services in training highly qualified personnel in Uzbekistan, he was awarded the title of Honored Scientist of Uzbekistan in 1981.

14 teachers who defended themselves under his scientific supervision became candidates of physical, mathematical and technical sciences. During this period alone, 11 doctors of sciences were graduated.

And from 1992 to 1994, Bannob Otakulovich entered the position of rector of the Fergana State Pedagogical Institute for the second time, which has already become the Fergana State University. As rector, he brought to the fore the issue of the preparation of candidates and doctors of sciences, focused on the scientific activities of the university, as well as to improve the financial base of this scientific center. Thanks to this, he managed to raise the status of the university to one of the leading higher educational institutions in the country.

For exemplary activity in the process of training scientific and pedagogical personnel, he was awarded a diploma of the Presidium of the Supreme Republican Council and the Ministry, and also became a medalist in the field of education of the Republic and the All-Union scale. In 1972—1986 he was a deputy of the Fergana Regional Assembly of Deputies.

The famous scientist, organizer and leader, outstanding mentor Bannob Otakulov left this mortal world in 2022 on January 2 at the age of 91.

Аннотация. Современные научные исследования прогрессивно развиваются, обещая наличие новых результатов. Одним из них является открытие и популяризация физики резонансных ядерных реакций в энергетическом плане. Особенностью данного раздела физики ядерных реакций является то, что возвращается вопрос об эффективности обычных экзо-энергетических ядерных реакций при проведении на ускорителях.

Ключевые слова: монохромотизация, резонансные ядерные реакции, ядерная физика, ускоритель заряженных частиц.

Annotation. Modern scientific research is progressing progressively, promising new results. One of them is the discovery and popularization of the physics of resonant nuclear reactions in the energy plan. The peculiarity of this section of nuclear reaction physics is that the question of the effectiveness of conventional exo-energetic nuclear reactions when carried out on accelerators returns.

Keywords: monochromatization, resonant nuclear reactions, nuclear physics, charged particle accelerator.

As is known, nuclear reactions are exo- and endo-energetic in nature, which divides them into categories according to the absorption and release of energy during the passage of the energy itself, due to the difference in the masses of the initial and resulting particles. At the same time, if the energy characteristics of these reactions were preserved, then the situation related to the number of interacting particles along the specified reaction channel becomes a big question, because any other interaction can also take place, due to the probabilistic nature of the behavior of such processes.

But as it turned out, the increase in the number of particles involved in the interaction increases when their energy approaches certain values – resonances, which are already more precisely defined today. But one aspect remained quite interesting and this is the question of the approximation of energy to a certain limit – the Coulomb barrier of the nucleus. Indeed, this barrier is not large in its dimensions, moreover, there is an additional energy spread due to ionization, which, fortunately, can already be calculated more accurately, for this reason, if we take into account all the ionization losses of the target substance, as well as the Coulomb barrier, as a result, the particle will have a sufficiently small nuclear gap energy. Here it is appropriate to recall the theory of dualism, according to which each particle is also a wave, and since the energy of the particle in the nucleus becomes minimal, its wavelength begins to grow, creating opportunities for interaction directly with the nucleus, excluding other probabilistic cases, which include the tunneling effect or scattering with elastic collision.

It seemed that this was not an effective procedure, since initially it was necessary to at least get into the Coulomb barrier itself, but due to sufficient beam density, as well as the effect of a monochromotizer, a theoretical result was obtained that greatly increases the efficiency of the entire reaction. For comparison, with only a boron-proton reaction with the release of 3 alpha particles on a thin 13 micron target, the effective cross-section of the nuclear reaction increases sharply and 99.999972% of all particles interact even at low currents, for a beryllium-proton-lithium reaction with the same alpha particles, this indicator is almost 100%, with the necessary accuracy. But there are also reactions with low efficiency, for example, proton-lithium-6 reactions with two alpha particles has an efficiency of only 65.53%, but at the same time having a large energy output.

The monochromotizer, which was mentioned earlier, is a device that separates a beam in a magnetic field by energy, after which a nano-structural substance – a carbon mesh – falls in its path, between the walls of the tubes of which there is a thin layer of a dielectric element or compound. At the same time, the induction vector of such an installation varies by a value of the order of 0.1 T and it can be noted that when the beam is deflected, a spectrum with a width of 0.327 mm is observed, while the wall thickness is measured in tens of nanometers, when the diameter of one inner tube is 0.572 microns, and the outer one is 0.636 microns. Losses at the same time exist and due to the "impact" on the walls of the tubes, up to 12.5% of the total number of charges is consumed.
