Applicability of the QsUb(Gg)-Systematics to the Description of Cross Sections for Multinucleon Transfer Reactions Induces by exp 40 Ar, exp 86 Kr, and exp 136 Xe Ions

摘要

Relative cross sections have been calculated for the production of gold isotopes with mass numbers of the 190-199 MeV range in the exp 181 Ta+ exp 40 Ar, exp 181 Ta+ exp 86 Kr and exp 181 Ta+ exp 136 Xe systems at laboratory bombarding energies of 290, 550 and 840 MeV, respectively. It was assumed that gold isotopes were produced as a result of multinucleon transfers followed by neutron evaporation. The yield of primary gold isotopes was found using the Qsub(gg)-systematics, whereas the neutron evaporation process was calculated within the framework of the Jackson model. The parameters used in the calculation are the average entrance angular momentum anti l, temperature UPSILON and the nuclear parameter r sub 0 of exit reaction channels. For realistic values of the parameters indicated a good agreement with the experimental data obtained previously has been achieved. This provides evidence for the applicability of the Qsub(gg)-systematics to the description of multinucleon transfer reactions induced by very heavy ions. (Atomindex citation 09:406352)
