Abstract
New 8(+) isomers in Se-82 and Ge-80 and their decays were studied by observ ing gamma rays from the projectilelike fragments produced by the deep-inela stic collision Pt-198+ 743 MeV 82Se. The lifetimes of the 8(+) isomers have been measured to be T-1/2=6.6(4) ns and T-1/2>0.4 ns for Se-82 and 80Ge, r espectively. The N=48 isotones from Ge-80(32) to Pd-94(46) turned out to sh ow quite different energy spectra of the yrast states up to I-pi =8(+), dep ending on the orbital occupied by valence protons.
