Abstract

Angular distributions of neutron groups from the 26 Mg( 3 He, n) 28 Si reaction have been measured at bombarding energies of 23.1 and 45.5 MeV. The experimental results are compared with DWBA and coupled-channel calculations. The zero-range DWBA calculation using shell-model two-nucleon spectroscopic amplitudes explains rather well most of the experimental data of the lowest four states in 28 Si, but it is necessary to take two-step processes into account to reproduce all of them satisfactorily. A strong neutron group observed at about 6.9 MeV in residual excitation is described as one composed of unresolved four groups, of which three are attributed to positive-parity states in 28 Si predicted in this energy region by the shell-model calculation and one to the 6.88 MeV 3 - state in 28 Si.
