Previous and Current Research

  • Gamma-emission from equilibrium and pre-equilibrium states
  • Statistical description of nuclear reactions including preequilibrium particle- and gamma- emission
  • Excitation and damping of collective states in hot atomic nuclei within framework of the semiclassical kinetic equation approach
  • Memory effects in collision integral
  • Effects of excitation and damping vibrational states on nuclear level density.
  • Shape evolution of giant dipole resonance
  • Average description of the gamma-transition in Fermi-systems
  • SCOPUS/GOGLE SCHOLAR h-index = 13/18; total citations = 1323/2428; SCOPUS author ID: 6603091172


Future Projects and Goals

Methods and related parameters for modelling gamma-ray cascades due to the gamma-transitions in highly excited nuclei will be reviewed. Analytical expressions for the photon strength functions (PSF) will be done with allowance for low-energy enhancement due to the nuclear structure effects (presence of low-energy resonance). The models and formulae previously recommended for the PSF will be updated, additionally tested and validated. Recommended sets and systematics of the parameters for PSFs calculations will be prepared. Computer code for PSF calculations within recommended models will be prepared and adopted for the use in the different codes for nuclear reaction calculations. Applications of the results to the gamma transitions in different nuclear processes (neutron induced nuclear reactions, isomeric ratios of primary fission fragments) will be considered.


Methodological and Technical Expertise

Reliable theoretical and clear physical methods will be applied.

Final expressions for the average description of gamma-transitions will be tested and validated with the use of modern experimental data.
