Abstract
The high-spin stales of Gd-155 were investigated by means of multiple Coulomb excitation with a 390-MeV Zr-90 beam. The members of the groun d-state rotational band of Gd-155 were assigned up to (31/2(-)). The m embers of a positive-parity side band were also strongly excited up to high spins (33/2(+)) with populations comparable to those of ground-b and members. The experimental population is compared with Coulomb-exci tation calculations taking account of the recommended upper limits for E1 and E3 strengths compiled in the whole mass region. It turns out t hat an E1 and/or an E3 strength larger than those limits would be nece ssary to account for the experiment.
