Giant neutron halo in nuclei beyond beta-stability line
V. M. Kolomietz, S. V. Lukyanov, A. I. Sanzhur
The radii of nucleon distribution and neutron skin in nuclei beyond the β-stability line are studied within the extended Thomas-Fermi approximation. We show that the growth of neut…
Symmetry Energy for Nuclei Beyond the Stability Valley
V. M. Kolomietz, A. I. Sanzhur
We apply the direct variational method to derive the equation of state for finite nuclei within the stability valley. The extended Thomas-Fermi approximation for the energy functio…
Isovector response and energy-weighted sums in hot nuclei
V. M. Kolomietz, S. V. Lukyanov, O. I. Davidovskaya
We investigate the collective response function and the energy-weighted sums (EWS) for isovector mode in hot nuclei. The approach is based on the collisional kinetic theory a…
Isovector energy-weighted sums for hot nuclei in presence of relaxation processes
V. M. Kolomietz, S. V. Lukyanov, O. I. Davidovskaya
We investigate the collective response function and the energy-weighted sums m_k for isovector mode in hot nuclei. The approach is based on the collisional kinetic theory and takes…
A dependence of the enhancement factor in energy-weighted sums for isovector giant resonances
V. M. Kolomietz, S. V. Lukyanov
We consider the energy weighted sums (EWS) for isovector giant dipole resonances (IVGDR) in finite nuclei within Landau kinetic theory. The dependence of both IVGDR energy, $E_{IVG…
Energy weighted sums for collective excitations in nuclear Fermi-liquid
V. M. Kolomietz, S. V. Lukyanov, O. O. Khudenko
Model independent, , adiabatic, , and high-energy, , energy weighted sums for the isoscalar and isovector nuclear excitations are investigated within the framewor…
