33Cl Spectroscopic Factors Via the 32s(3he, D)33cl One-Proton Transfer Reaction

The structure of light-to-medium mass nuclei is crucial to understand exotic phenomena in nuclear structure, including the appearance of molecular effects in light nuclei and their impact in nuclear astrophysics. In this paper, a new experiment to probe one-proton spectroscopic factors of bound and unbound states in the sd-nucleus Cl-33 is discussed. The experiment exploits the reaction S-32(He-3, d)Cl-33* at 9:68 MeV bombarding energy. This reaction is suitable to probe the single-particle structure of Cl-33 states with respect to the population of 1d(3/2), 1f(7/2) and 2p(3/2) shells. Crucial aspects of the investigation are the use of an enriched, high-purity, S-32 target and a new generation hodoscope with improved angular resolution, allowing to obtain high-precision angular distribution of the differential cross section in a broad angular range. Results are interpreted by means of finite-range DWBA and coupled-channel calculations.
