Abstract

The recently proposed matrix-coherent state approach for configuration mixing IBM is used to describe the evolving geometry of the neutron deficient Pt isotopes. It is found that the Potential Energy Surface (PES) of the Platinum isotopes evolves, when the number of neutrons decreases, from spherical to oblate and !hen to prolate shapes, in agreement with experimental measurements. Oblate Prolate shape coexistence is observed in 194,192pt isotopes. [ABSTRACT FROM AUTHOR]

5. Excited bands in even-even rare-earth nuclei.

*RARE earth nuclei, *DYSPROSIUM, *ISOTOPES, *NUCLEAR shell theory, *NUCLEAR models
Abstract

The energetics of states belonging to normal parity bands in even-even dysprosium isotopes, and their B(E2) transition strengths, are studied using an extended pseudo-SU(3) shell model. States with pseudospin 1 are added to the standard pseudospin 0 space, allowing for a proper description of known excited normal parity bands. [ABSTRACT FROM AUTHOR]
