Abstract
ΔJ=1 band structures were found in the doubly odd ,122Cs and ,128La nuclei via γ-ray spectroscopy following heavy-ion-induced reactions. The band characteristics for the Z>50 transition region (non-staggered spacings and positive E2/M1 mixing ratios), that are associated with the proton-hole intruder, were observed in , but changed to significant staggering and negative mixing ratios along with increased E2 crossover branching in the other three nuclei.
