Studies of Evaporation Residue Products from Krypton and Argon Reactions

摘要

Mass distributions of evaporation residue (ER) products from exp 86 Kr-bombardments of exp 70 Ge and exp 74 Ge were obtained by a time-of-flight method at energies ranging from the interaction barrier to 706 MeV. ER excitation functions were also obtained for a variety of target and projectile combinations. Results are compared with statistical model calculations and with results obtained from gamma -measurements. It is deduced that at the lowest impact parameters, the reaction products belong to the ER group, in contrast with the angular momentum hypothesis of Lefort. Cross sections were found to be consistent with an angular momentum limit arising from the onset of fission. (ERA citation 03:038516)
