Excitation of the 9·50 MeV (9/2+) State of ¹³C in Intermediate Energy Scattering Experiments

Abstract

The differential cross section for the inelastic scattering of 135 MeV protons leading to the9/2+ (9·5 MeV) state in ¹³C has been measured. Microscopic DWBA analyses show that the angular distribution is well described by a pure (or nearly pure) 1p_3/2 to 1d_5/2 neutron transition with a total angular momentum transfer of 4, a description which is consistent with the previously observed large asymmetry in inelastic π+ and π- scattering to this state.
