Observation of the $0^+_2$ state in $^{44}$S

Abstract : We report preliminary results on the observation of the isomeric $0^+_2$ state in $^{44}$S. This state, populated in the fragmentation of a $^{48}$Ca beam, is located at 1365$\pm$1 keV and has a half-life of 2.3$\pm$0.3 $\mu$s. The observation of this isomer is the first experimental evidence of shape coexistence in $^(44}$S which was predicted by various theoretical approaches. In particular, we found a good agreement with shell model calculations.
