Abstract

Band crossings are observed in the yrast =-12 and +12 negative-parity decay sequences in Ho157 at =0.48 and 0.54 MeV, respectively. These band crossings are interpreted as the alignment of the second and probably the third pair of h112 quasiprotons. This is the first identification of delayed crossings involving the second aligning nucleon. These crossings show that sizable proton-pair correlations must remain for these configurations up to high rotational frequencies 0.5 MeV.
