Decays of millisecond isomers in odd-oddN=81 nuclei146Tb,148Ho and150Tm

Abstract

Following reactions induced by 245 MeV60Ni ions, isomers have been identified in the odd-oddN=81 isotones146Tb,148Ho and150Tm with half-lives of 1.18(2), 2.35(4) and 5.2(3) ms, respectively. Their decays have been characterized byγ-ray spectroscopy. The isomers are interpreted as (πh 11/2 νh 2/−11 ) 10+ states decaying to members ofπh 11/2 νd 2/−13 andπh 2/−111 multiplets. The observed level spectra and M1 branching ratios are found to be in good agreement with shell model predictions based on empirical and Schiffer-Trueπν −1 residual interactions.
