Abstract

The C13(He3, α)C12 reaction was studied at 12, 15, and 18 MeV. Complete angular distributions of elastically scattered He3 as well as those of α particles leading to the ground, 4.433-, 7.656-, 9.64-, 10.84-, 11.83-, and 12.71-MeV states were measured. A set of optical-model parameters that fits the elastic-scattering cross section of He3 at all three energies was found with the hunter program. It shows only a slight negative energy dependence of the real well depth and a positive energy dependence of the imaginary well depth. Distorted-wave Born approximation (julie) analysis shows pickup of l=1 or 0 for all excepting the 9.64-MeV state, where l=2 is found. Relative spectroscopic factors were extracted.
