Shape Transition to a Rare Shape Phase of Prolate Non-collective in A = 100 Isobars

TL;DR

This paper investigates shape transitions in A=100 isobars, revealing a rare prolate non-collective shape phase on the proton-rich side, influenced by neutron number, temperature, and spin.

Contribution

It introduces the observation of a rare prolate non-collective shape phase in A=100 isobars, expanding understanding of nuclear shape transitions in this mass region.

Findings

Multiple shape transitions observed across isotopes.

Prolate non-collective shape identified as a rare phase.

Shape transitions influenced by temperature and spin.

Abstract

A theoretical investigation on the shape transitions with neutron number, temperature and spin for A $=$100 isobars of Z$=$42 to 50 is presented. A variety of shape transitions are observed while moving from neutron rich 100 Mo to proton rich 100 Sn with predominant triaxial shapes. Temperature and spin induced shape transitions are explored within the microscopic theoretical framework of and statistical theory of hot rotating nuclei. Prolate non-collective which is a rare shape phase is reported in this mass region on the proton rich side of the nuclear chart.
