Abstract

Three odd-odd N = 73 isotones, namely ¹²⁸Cs, ¹³⁰La, and ¹³²Pr, have been studied via (HI, xnγ) reactions. In all three cases, ΔI = 1 side bands of the πh_11/2vh_11/2 yrast bands were discovered. This extends the systematic observation of nearly degenerate πh_11/2vh_11/2 doublet bands in the neighboring N = 75 isotones; these were interpreted as resulting from chiral symmetry breaking in the intrinsic body-fixed frame.
