Sažetak
Excited states of the neutron-rich N=21 37S nucleus have been studied using binary grazing reactions produced by the interaction of a 215- MeV beam of 36S ions with a thin 208Pb target. The magnetic spectrometer, PRISMA, and the γ- ray array, CLARA, were used in the measurements. The level scheme of 37S was established to an excitation energy of 4196 keV and a number of new transitions were observed, in particular that corresponding to the decay of the proposed (11/2−) level at an excitation energy of 2776 keV. The structure of the state is discussed within the context of state-of- the-art shell-model calculations using the SDPF-U effective interaction ; the main component of the wave function corresponds to the coupling of the odd 1f7/2 neutron to the first 2+ state of the 36S core. The electromagnetic decay properties of the state are discussed within the context of a particle- core coupling model and the shell model. The other members of the multiplet of states are also discussed.
