E1 gamma-transitions in hot atomic nuclei

Abstract

New version of the modified Lorentzian approach for radiative strength function is proposed. Renewed systematics for giant dipole resonance (GDR) parameters is given. The gamma-decay strength functions are calculated using renewed GDR parameters and compared with experimental data. It is demonstrated that closed-form approaches with asymmetric shape of the gamma strength, as a rule, provide the reliable simple method for description of gamma-decay processes.
