Query: Configuration mixing description of the nucleus $^{44}$S   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.
