Abstract

Nuclear level density (NLD) and radiative strength function (RSF) are\ndescribed simultaneously within a microscopic approach, which takes into\naccount the thermal effects of the exact pairing as well as the giant\nresonances within the phonon-damping model. The good agreement between the\nresults of calculations and experimental data extracted by the Oslo group for\n^{170, 171, 172}Yb isotopes shows the importance of exact thermal pairing in\nthe description of NLD at low and intermediate excitation energies and\ninvalidates the assumption based on the Brink-Axel hypothesis in the\ndescription of the RSF.\n
