UNBONDED EXCITED STATES OF NUCLEI, CLUSTERS, MONTE CARLO MODELING METHOD, TIME STAMP, CORRELATION EXPERIMENT, RADIONUCLIDE PHARMACEUTICALS, ISOTOPIC CYCLOTRONS, BEAM ONCOTHERAPY, NEUTRON DETECTORS, KINEMATIC CURVE, PROJECTION Object of research - three-four particle nuclear reactions on the lightest nuclei. The purpose of the work is to experimentally study the features of the structure of the excitation spectra of the nuclei 4Не,5Не, 5Li 6Не, 6Li, 6Ве, 8-9Ве and 12С, which mainly consist of unbound excited states using a correlation study of nuclear reactions caused by the interaction of proton beams, deuterons, alpha particles with the nuclei 2Н,3Н, 3Не. 6, 7Li, 9Бе, 10, 11B, 12C Research methods - modernization of existing experimental correlation techniques on INR accelerators to increase the efficiency of using measurement time using a modern multi-channel measurement system. An improved parameterization of inclusive proton spectra from the 3Н(α, p)6Нe reaction was carried out using the results of a correlation study. A review and evaluation of neutron detectors with sufficient efficiency, energy resolution and time characteristics for the correlation method was made. A program was developed for designing experimental data onto a kinematic curve and converting two-dimensional spectra into one-dimensional ones using the E1/E2 method. The possibility of creating a scientific and technical enterprise at the Institute of Nuclear Research of the National Academy of Sciences of Ukraine for the production of a wide range of radiation isotopes and radionuclide pharmaceuticals based on them was considered. An overview of accelerators and technologies was given in order to determine the optimal solutions for Ukraine. A device was developed for obtaining isotopes on the internal proton beam of the U-240 cyclotron. A target was designed for obtaining the 22Na isotope in difficult conditions of thermal and Product Description popup.authors Voiter Anatolii P. Horpynych Olha K. Doronin Mykhailo I. Maznyi Ivan O.
