The spherical to asymmetric shape transition in the mass region with 50<(N, Z)<82

Study of the124Xe and126Xe structure

“…Potentials for 7 =0~ 25~ 60~ are presented. There are no data for lZ~Xe in [26,27] inertial functions BT~, Bx, By, Bz, the results obtained using model I with B~v = B x = By = B z = const = B .... Another attempt to interpret the properties of lowlying excited levels for even-even nuclei from the 50<Z, N__<82 region by collective quadrupole excitations was described by Habs et al [26,27]. They used the model (modelIII) of Gneuss and Greiner [28].…”

Spins, moments and charge radii in the isotopic series181Hg-191Hg

“…** Obviously, moreB(E2, 2~0)values for deriving (/~2) are desired. In view of the complex potential energy surface of very light Hg isotopes, it might be preferable, however, to overcome the shortcomings of (15) by a refined semiempirical analysis, e.g., on the lines of Cline [34] or using the Gneuss-Greiner Code [35], both requiring much more spectroscopic information.…”

Laserspectroscopic studies of collective properties of neutron deficient Ba Nuclei

“…This is due to the fact that these nuclei provide a crucial testing ground for nuclear structure models which try to describe the collective degrees of freedom on a phenomenological or microscopic basis. The analyses of the level spectra and decay properties of the even-even nuclei in the mass region 50<(N,Z)< 82 have revealed [3] 7-soft shapes of increasing rms deformation with decreasing neutron number and indicate a shape transition via the ? degree of freedom.…”
