Obtaining of nuclear level density and radiative strength functions when analysing (n, 2γ) reaction

Publications, 13 December 2022

We offer to your attention a preprint “Possibility of simultaneous obtaining of the nuclear level density and radiative strength functions when analysing (n, 2γ) reaction” E3-2022-43 published by the JINR Publishing Department. The authors are Anatoly Sukhovoj, Ludmila Mitsyna.

For 43 compound nuclei from the 40 ≤ A ≤ 200 mass region, the most probable nuclear-physical parameters (the radiative strength functions and nuclear level density) were accumulated obtained by the empirical method of analysis of precise experimental intensities of the two-step γ cascades in nucleus decaying after thermal neutron capture.

The method allows obtaining the strongly correlated nuclear-physical parameters from indirect experiment simultaneously which enables to investigate the intranuclear processes.

The results of the empirical analysis are presented for all investigated nuclei when testing versions of model representations of energy dependences of the required nuclear-physical parameters.

The research has been performed at the Frank Laboratory of Neutron Physics JINR.
