    Abstract

    Chirality is a distinct signature that characterizes triaxial shapes in nuclei. We report the first observation of chirality in the nucleus Pr135 using a high-statistics Gammasphere experiment with the Sb123(O16,4n)Pr135 reaction. Two chiral-partner bands with the configuration π(1h11/2)1⊗ν(1h11/2)−2 have been identified in this nucleus. Angular distribution analyses of the ΔI=1 transitions connecting the two bands reveal a dominant dipole character, and quasiparticle triaxial rotor model calculations show good agreement with the data. Since the simultaneous observation of chirality and transverse wobbling in Pr135 relies critically on these angular distribution results, we also address and refute the experimental and theoretical criticisms raised in a recent work by Lv et al., presenting additional evidence that further strengthens our interpretation. This marks the first observation of both hallmarks of triaxiality—chirality and wobbling—in the same nucleus.
