Description of the even-mass Hg and Pt isotopes by a microscopic collective hamiltonian

The o-factors of the 2] and 4] states in 198,2oo, 2O2Hg were simultaneously measured by means of the transient-field perturbed angular correlation method in Coulomb excitation using multi-isotopic targets and thin polarized Gd foils as ferromagnetic host. The g(2[) and 9(4 ~) were found identical within errors in ~ 98,2OOHg ' while in 2~176 lower o-factor values have been determined. The experimental 0-factors were compared with the predictions of the pairing-plus-quadrupole, dynamical deformation and interacting boson models.

A microscopic calculation of Bohr's collective Hamiltonian is used to describe the collective motion in the 76Kr isotope. A single-particle basis calculated in a deformed Woods-Saxon potential leads to the potential energy surface obtained by the Strutinsky renormalization procedure, and to the inertial functions determined in the cranking model approximation. The collective Schr6dinger equation is solved numerically. The low-energy, even parity states in 76Kr are analyzed in the frame of this model. The theoretical results involve the potential energy and the inertial parameters as functions of intrinsic quadrupole deformations, the collective levels and wave functions including their transitions and electromagnetic moments. A good agreement between experiment and theory is obtained without adjusting specifically for this nucleus any parameter in the model. Some results regarding statical and dynamical characteristics of even-even 74'TS, S~ isotopes are also presented.
