Excited states of the odd-odd nucleus 122Ⅰ are investigated via the fusion-evaporation reaction 116Cd(11 B,5n) at a beam energy of 68 MeV.The two most strongly populated bands in 122Ⅰ are observed up to excitation energies around 10.5 MeV.Their possible configurations at lower spins are assigned to πh11/2 (x) vh11/2 and πh11/2 (x) vd5/2 based on the observed population,B(M1)/B(E2) values,alignments and signature splitting.E1 transitions are observed connecting the πh11/2 (x) vds/2 band to the πh11/2 (x) vh11/2 band,which may be evidence of octupole collectivity.Band terminations caused by the full alignment of the valence nucleons outside the 114Sn core are observed in both bands.
