Abstract
The structure of the S nucleus has been studied at GANIL through the one proton knock-out reaction from a Cl secondary beam at 42 AMeV. The rays following the de-excitation of S were detected in flight using the 70 BaF detectors of the Château de Cristal array. An exhaustive -coincidence analysis allowed an unambiguous construction of the level scheme up to an excitation energy of 3301 keV. The existence of the spherical 2 state is confirmed and three new -ray transitions connecting the prolate deformed 2 level were observed. Comparison of the experimental results to shell model calculations further supports a prolate and spherical shape coexistence with a large mixing of states built on the ground state band in S.
