New investigations on the 32S(3He,d)33Cl reaction at 9.6 MeV bombarding energy

The S-32(He-3,d)Cl-33 one-proton transfer reaction is a powerful tool to investigate the spectroscopy of low-lying states in the proton-rich Cl-33 nucleus. However, the extraction of firm differential cross-section data at various angles to benchmark and constrain theoretical models is made challenging by the presence of competitive reactions on target contaminants In this paper we report on a recent measurement using a new generation hodo scope of silicon detectors, capable to detect and identify emitted deuterons down to energies of the order of 2 MeV. The high angular segmentation of our hodoscope combined with a suitable target to control possible contaminants, allowed to unambiguously disentangle the contribution of various states in Cl-33 in particular the 2.352 MeV state lying just few tens of keV above the proton separation energy.
