We report preliminary results on the observation of the isomeric 0+ 2 state in 44S. This state, populated in the fragmentation of a 48Ca beam, is located at 1365±1 keV and has a half-life of 2.3±0.3 μs. The observation of this isomer is the first experimental evidence of shape coexistence in 44S which was predicted by various theoretical approaches. In particular, we found a good agreement with shell model calculations.
