Highly Deformed Shape Structure in $^{160,161}$Tm

ORAL

Abstract

The recent discovery of four rotational bands displaying characteristics of triaxial superdeformation (TSD) in $^{157,158}$Er bands has opened a new high spin dominion near N$\sim$90 in the rare-earth region [1]. However, evidence on neighboring nuclei is necessary to develop a more complete understanding of this phenomenon. In an experiment performed at the Argonne Tandem Linear Accelerator System (ATLAS) using the Gammasphere detector array, similar highly deformed band(s) in $^{160,161}$Tm have been found and will be discussed.
