A study of the Si-30(d,p)Si-31 reaction

The reaction Si-30(d,p)Si-31 is studied at the incident deuteron energy of 12.3 MeV. Proton groups are analysed using a multi-angle magnetic spectrogr aph with the resolving power E/Delta E approximate to 1000. Angular distrib utions of proton groups corresponding to 14 bound states and to 8 unbound. states of the Si-31 nucleus are analysed using DWBA calculations, Deduced t ransferred orbital angular momenta and spectroscopic factors differ for som e states from those obtained previously. In particular, we attribute l = 1 transfer to the state at 5.281 MeV. Shell-model calculations are performed in a complete 0h omega model space for positive-parity states and in a rest ricted 1h omega model space including f7/2, p3/2 and p1/2 neutron orbits fo r negative-parity states. The excitation energies as well as spectroscopic strengths of most of strongly excited positive- and negative-parity states are reasonably well interpreted within the shell model.
