A Search for Evaporation Residues in Reactions of Chlorine on Thulium and Gold.

摘要

Recoiling evaporation residues from the fusion of Cl 37 and two proton rich nuclei, Tm 169 and Au 197, were studied at lab energies of 151 through 186 MeV, and 176 through 184 MeV, respectively. The zero degree excitation function was measured for the Tm reaction (compound nucleus Rn206) and was found to peak at 156, 167, 177, and 182 MeV corresponding to emissions of 3n, 4n, 5n, and 4n-1p, respecitvely, with a maximum total cross section of 1.09 millibarns, occurring at 166 MeV.
