Abstract
The reaction to the first excited state of (2.31 MeV, , 1) was investigated for isospin nonconservation. Angular distributions were taken for nine incident deuteron energies between 5 and 10 MeV. The symmetries observed in the angular distributions indicate a predominantly compound-nuclear reaction mechanism. The observed violation arises most probably from "Coulomb mixing" in the compound nucleus. The measured cross-section ratio of the first to the second (3.95 MeV, , 0) excited state of varied from 3 to 1% for deuteron energy increasing from 6 to 10 MeV. The region of excitation of between 26.0 and 31.0 MeV was investigated by measuring the excitation function for inelastic deuteron scattering to the second excited state of for deuteron energies between 5.9 and 12.2 MeV at a laboratory angle of 60°. Gross structure was observed at excitation energies of 27.2 and 29.6 MeV in . The presented data are compared with photoabsorption data for this range of excitation energy.
