Abstract

The ground-state rotational bands of Gd155 and Gd157 have been investigated through multiple Coulomb excitation with beams of 240-MeV Ni58 and 305-MeV Br81. Gamma-ray branchings and E2/M1 mixing ratios were determined by γ-ray angular-distribution measurement. Nuclear lifetimes of levels up to I=21/2 and 23/2 for Gd155,157, respectively, have been measured using the Doppler-shift recoil-distance method. The observed signature dependence of M1 transition rates was found to be inverted in relation to the quasiparticle energy splitting. The data are analyzed in terms of the cranking model.
