The basic research areas

The experimental and theoretical researches of particles interaction processes with nucleons and nuclei in wide energy range of particles-projectile, as well as development the new methods and facilities for fundamental and applied researches.

The basic research results for the last 5 year

For experimental research:

  • The bilateral high-transmission spectrometer was developed in energy range up to 500 МeV and a lot of experiments on searching of dinucleon resonances in the field of effective mass of two protons from 1.97 up to 2,21 GeV were implemented in collaboration with physicists of Joint Institute for Nuclear Research(JINR-Dubna, Russia), Triumph nuclear centre(Vancouver, Canada) and Washington University (Seattle, USA). The results have been published;

  • The excitation elastic scattering functions of protons were measured in carbon with energy resolution ~10 кeV at unique measuring complex “cyclotron-magnetic spectrograph” of INP AS RU. Tests results allows to tell about the availability of new type effects- combination isobar resonance;

  • To implement precise works, the experimental device-mass spectrometer is used at the nuclear reactor for unmoderated fission nuclei products, in which was received results, pointing out to super-asymmetric fission mode of heavy nuclei. The measurement data are well matched with accomplished measurements in Grenoble (France), the results and development experience of mass-spectrometer were used for calculation and producing transit time device –double-arm mass-spectrometer for the reactor “"ПИК" (Gatchina, Russia.)

The number of theoretical developments regarding to the energy calculation models of primary excited states of nucleons were conducted taking into account single-gluon and single-mesonic direct and exchange diagrams second order, as well as using rules of sums including the isoscalar and isovector transitions and taking into account nonorthogonality for the control precision of wave functions of 3H and 3He nuclei. These works were published and currently used in research centres of Germany, Italy and Denmark.

For biomedical applications, the new method of gaining three-dimensional positron emission tomographical images have been developed, as the basis for development three-dimensional positron emission tomography-scanner of new generation, for medical diagnostic and therapeutic practice, the device-reograph has been developed which allows conducting the automatic monitoring of patient blood circulation.
