Abstract
High-spin states in Xe-124 were populated in the fusion-evaporation reactio n Pd-110(O-18,4n) Xe-124 at a beam energy of 86 MeV. The experiment was per formed at the NORDBALL spectrometer in Riso, Denmark. The decay out of a ma gnetic dipole band was established for the first time in this nucleus. By m eans of angular correlations from oriented states the multipole mixing rati os for 9 of the 12 gamma transitions of the magnetic dipole band were deduc ed. The experimental B(M1;I-->I-1)/B(E2;I-->I-2) values were compared to es timates of the Donau-Frauendorf semiclassical model. The dipole band is inf erred to be based on a prolate four-quasiparticle configuration of the type [nu(h(11/2)xg(7/2))]x[pi(h(11/2)xd(5/2)/g(7/2))].
