Configuration mixing description of the nucleus ⁴⁴S
read the original abstract
We study the structure of the neutron rich $^{44}$S isotope with modern configuration mixing methods based on the Gogny interaction including beyond-mean-field effects. Restoration of particle number and rotational symmetries are taken into account as well as shape mixing in the whole triaxial $(\beta_{2},\gamma)$ plane. We obtain a qualitative agreement between the calculated spectrum and the experimental data reported recently. Very extended collective wave functions in the $(\beta_2,\gamma)$ plane are found for the lowest states, corresponding to very flat potentials, indicating strong configuration mixing and supporting the weakening of the N=28 magic number.

Multireference covariant density functional theory for shape coexistence and isomerism in $^{43}$S
MR-CDFT calculations for 43S identify the ground state as dominated by a prolate intruder 1qp configuration, the 7/2-1 as a high-K prolate isomer, and the 3/2-2 as an oblate-prolate admixture.
