    Notes: Abstract The nature of the ground and theγ band is studied in the asymmetric rotator model for larger asymmetric deformationsγ and higher angular momenta. Properties of theγ band are found which may make it possible to search experimentally for staticγ deformations. Sum rules for quadrupole moments and energies are derived. For the description of higher angular momenta the softness of the nucleus is included by an extension of the VMI model to asymmetric deformations. Energies, quadrupole moments andE 2 transitions are given for the Os region and compared with the available data.

    Notes: Abstract Excited levels of143Eu have been investigated by nuclear spectroscopy methods. We measured γ-rays and conversion electron singles spectra as well asγγ-coincidences from mass separated143mGd sources (108 s) prepared after the irradiation of144Sm with 78 MeVα-particles. In addition in-beam data were obtained by measuringγ-ray singles spectra, angular distributions andγγ-coincidences, following the144Sm(α, 4n+ p, γ) reaction. A level scheme for143Eu comprising 19 levels is proposed, spin assignments or at least restrictions are given. The deduced experimental level scheme can be reproduced semiquantitatively by a generalized decoupling model which takes into account an asymmetric deformation of the core and a variable moment of inertia. Additionally, the results are discussed in the limit of the weak coupling model.
