  Magnetic dipole bands have been identified in 142,143,144Gd and 141Eu nuclei.
The observed bands are based on configurations with small oblate deformation
involving high-Omega, h11/2 proton particles and low-Omega, h11/2 neutron
holes. Information about the strength of the effective interaction between the
constituent nucleons has been deduced using a semiclassical scheme of the
coupling of two angular momentum vectors. The experimental results are compared
with predictions of tilted axis cranking calculations. The transition from
irregular dipole band in 144Gd to more regular ones in lighter Gd nuclei is
observed.
