Abstract
Chirality is a distinct signature that characterizes triaxial shapes in nuclei. We report the first observation of chirality in the nucleus $^{135}$Pr using a high-statistics Gammasphere experiment with the $^{123}$Sb($^{16}$O,4n)$^{135}$Pr reaction. Two chiral-partner bands with the configuration $\pi(1h_{11/2})^1\otimes \nu(1h_{11/2})^{-2}$ have been identified in this nucleus. Angular distribution analyses of the $\Delta I = 1$ connecting transitions between the two chiral partners have revealed a dominant dipole character. Quasiparticle triaxial rotor model calculations are in good agreement with the experiment. This is the first time that both signatures of triaxiality--chirality and wobbling--have been observed in the same nucleus.
