Yrast bands in even-mass Pt and Hg isotopes

Abstract EN

A simple semi-empirical model based on the vibrational model is used to investigate the yrast bands of 178-188Pt and 182-198Hg isotopes.

Additionally, the model overcomes the effect of the shape coexistence and shape transitions.

This model gives a good fit to the observed small spacing between the 10+ and 12+ levels of 190Pt and the closely spaced triplet (8+, 10+ and 12+) structure in the energy spectra of 188-198Hg isotopes as compared with the other main models
