From chiral vibration to static chirality in $^{135}$Nd

ORAL

Abstract

Lifetimes were obtained in a DSAM measurement at Gammasphere, using the $^{100}$Mo($^{40}$Ar, 5n)$^{135}$Nd reaction. Electromagnetic transition probabilities have been measured for the intra- and inter-band transitions in the two sequences in the nucleus $^{135}$Nd that were previously identified as a composite chiral bands [1]. The measurements are in good agreement with results of a new combination of TAC and RPA calculations. The chiral character of the bands is affirmed and it is observed that their behavior is associated with a transition from a vibrational into a static chiral regime. [1] S. Zhu et al., Phys. Rev.
