摘要

Residual gold nuclei were produced via neutron transfer at multiple energies using a 130-MeV C-13 beam incident on a stacked-foil target consisting of alternating layers of Au-197 and Al-27. Production cross sections, over an energy range of 56 to 129 MeV, for seven gold isotopes and two gold isomers were determined through activation analysis. By using the Wilczynski binary transfer model with a modified version of the recoil formula and a standard evaporation model, we were able to reproduce the isotopic production cross sections at high beam energy, with some disagreement at lower beam energies. This limiting angular momentum model does not predict the transfer of sufficient angular momentum to reproduce the observed isomeric populations.
