Abstract

New experimental results on 43S and 44S reveal that these nuclei are located in a transitional region of shape coexistence between the spherical 48Ca and the oblate 42Si. The origin of the deformation is discussed in terms of the evolution of the single particle energy levels leading to the compression of the energy difference of the orbitals in the sd and pf shells for protons and neutrons, respectively. Therefore, due to quadrupole excitations across the Z = 14 and N = 28 gaps, the intruder configuration in the neutron rich S isotopes became the ground state. [ABSTRACT FROM AUTHOR]

Abstract

The results obtained from electron and in-beam spectroscopy experiments reveal that the 44S nucleus is located in a transitional region between the spherical 44Ca and the oblate 44Si. The comparison of the results with Large Scale Shell Model calculations points towards prolate-spherical shape coexistence where the ground state becomes the intruder configuration due to quadrupole excitations across the Z = 14 and N = 28 shell gaps.
