An Exploration of Structures in the Transitional Odd-Odd Nucleus $^{160}\textrm{Lu}$

ORAL

Abstract

It is known that a transition between spherical and deformed isotopes of lutetium occurs near $N=88$. The odd-odd nucleus $^{160}\textrm{Lu}$ ($N=89$) was selected for a study of structural characteristics in this transitional region. High-spin states of $^{160}\textrm{Lu}$ were populated using the $^{120}\textrm{Sn}(^{45}\textrm{Sc},5\textrm{n})^{160}\textrm{Lu}$ reaction and gamma-ray transitions were studied using the Gammasphere spectrometer. Known structures were extended to much higher spin and a new sequence was identified. The resulting bands and nuclear configurations were studied and compared with neighboring isotopes of lutetium.
