Abstract

High-spin states were populated in Hf172 with the Ca48+128Te reaction at 200 and 214 MeV. All of the known rotational bands in Hf172 have been extended and five new rotational bands have been observed using the Gammasphere spectrometer. This study establishes the highest known state in Hf172 at spin 44Latin small letter h with stroke. One of the new bands is a K=(14+) strongly coupled rotational band. In conflict with the K-selection rule another newly established bandhead state, with spin I=K=12, is observed to decay directly to the yrast 12+ state. This large breakdown in the K-selection rule (K12) may be due to a mixing between the low- and high-K states in Hf172.
