Abstract

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 πg_9/2^-1⊗νh_11/2 configuration, has been extended to I^π=(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.
