Description
Summary:Photoabsorption cross sections and γ-decay strength function are calculated and compared with experimental data to test the existing models of dipole radiative strength functions (RSF) for the middle-weight and heavy atomic nuclei. Ready-to-use tables of giant dipole resonance parameters with their errors are prepared. Systematics for GDR energy and width are given. It is shown that the phenomenological closed-form models with asymmetric shape can be used for overall estimates of the dipole RSF in the γ-ray energy region up to about 20 MeV, when GDR parameters are known or their systematics can be adopted.
