Abstract
Energy spectra of3He-particles from the (d,3He) reaction on28, 29, 30Si,31P and32S have been measured at an incident energy of 52 MeV. Spectroscopic factors have been determined by comparison of measured and DWBA angular distributions. The results are compared with predictions of recent shell model calculations. Excitation energies and spectroscopic strengths of low lying positive parity states are fairly well described. The 1d 5/2 hole strengths distributions are not reproduced. The measured 1p hole strength decreases rapidly from28Si to28S. The occupation numbers of the different subshells show a considerably smoothed Fermi surface of these nuclei.
