Evidence for the scissors mode in 160Tb from the two-step gamma cascades measurement

Popis výsledku v původním jazyce

Spectra of two-step ? cascades (TSCs) following the neutron capture in 159Tb were measured by the sum-coincidence technique with a two-HPGe-detector facility [1] installed at a pure sub-thermal neutron beam of the 15 MW light-water research reactor at Řež near Prague. In order to obtain information about the quantities governing the ? decay of 160Tb levels - the photon strength functions (PSFs) and the level density (LD) - experimental TSC spectra were compared with the output of simulations of the ? cascade decay based on the validity of extreme statistical model. These simulations were performed with the aid of the DICEBOX algorithm [2] assuming various combinations of the PSFs and LD. The results obtained lead to an inescapable conclusion that the Scissors Mode (SM) plays a crucial role in the cascade ? decay of the product nucleus 160Tb. This finding represents the first evidence for the existence of the SM in an odd-odd nucleus.
