Stability of chiral geometry in the odd-odd Rh isotopes: spectroscopy of 106Rh

The nucleus 106Rh was populated using the reaction 96Zr(13C, p2n) at a beam energy of 51 MeV. γ-ray transitions were identified using the EUROBALL-IV γ-ray spectrometer and the DIAMANT charged particle array. The yrast band, which is based upon a πg9/2−1νh11/2 configuration, has been extended to Iπ=(22−). A new ΔI=1 band has been identified which resides 300 keV above the yrast band. Core–quasiparticle coupling model calculations show reasonably good agreement with the data. The properties of the two pairs of strongly coupled bands are consistent with a chiral interpretation for these states.
