Microscopic calculation of the collective motion in76Kr

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

A microscopic calculation of Bohr's collective Hamiltonian is used to describe the collective motion in the76Kr 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 Schrödinger equation is solved numerically. The low-energy, even parity states in76Kr 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-even74, 78, 80Kr isotopes are also presented.
