Abstract

Results of single-neutron knockout experiments from 34,35Si at 73A MeV and from 37S at 69A MeV on a Be target are reported. The final states in the reaction residues have been identified by measuring γ rays in coincidence with the (A-1) fragments. The results are compared with predictions based on the many-body shell model combined with eikonal and transfer-to-the-continuum reaction models. For the 9Be(34Si,33Si+γ)X reaction, the measured parallel-momentum distributions of the reaction residues demonstrate the orbital-angular-momentum assignments l=2, 0, 2 to levels at 0, 1.010, and 4.32 MeV (adopted values). The measured absolute spectroscopic factors exhaust a large fraction of the sum rules for a full (N=20) sd shell. We also give results for the absolute and relative positions of the parallel-momentum distributions and present experimental and theoretical results for the complex spectra of the 9Be(35Si,34Si+γ)X reaction. The measured inclusive cross section of 106(19) mb agrees well with the theoretical value of 98 mb, but more detailed conclusions are not possible. For the inclusive reaction 9Be(37S,36S)X a cross section of 99(12) mb is found compared to the theoretical prediction of 85 mb where only final states with spectroscopic factors greater than 0.03 have been included.
