Abstract
High-spin states in the doubly odd N=75 nuclei Pm-136 and Eu-138 were popul ated following the Sn-116(Mg-24,p3n) and Cd-106(Cl-35,2pn) reactions, respe ctively. A new DeltaI = 1 band is reported in Eu-138 and new data are prese nted for the recently reported band in Pm-136. Polarization and angular cor relation measurements have been performed to establish the relative spin an d parity assignments for these bands. Both bands have been assigned the sam e pih(11/2)x nuh(11/2) structure as the yrast band and are suggested as can didates for chiral twin bands.
