Energy gain evaluation for heavy ion fusion-fission reactor of 16O + 209Bi, 32S + 181Ta and neutron rich projectile reaction of 38S + 181Ta

Abstract

The energy for heavy ion interaction of ¹⁶O + ²⁰⁹Bi and ³²S + ¹⁸¹Ta is considered here. These reactions have considerable fusion cross-section and the compound nucleus formed makes fission immediately. For the proposed thick target and calculated number of emitted neutrons, the energy gains of 15.6 and 9 are obtained respectively. To evaluate our used theories here, ¹⁶O + ¹⁹⁷Au reaction is used. Existing reliable experimental information on this reaction greatly helped in application of the used theory for it and the obtained gain is 17.5. In continuation of our gain studies we calculated the gain for neutron rich projectile of ³⁸S on ¹⁸¹Ta. The obtained energy gain is 13 which is 1.5 times the gain ³²S + ¹⁸¹Ta reaction. This increase is due to a reduction on the fusion potential barrier which results in fusion cross-section enhancement. Finally, comparison of obtained results with the gain of other designs of light ion fusion systems suggests that the proposed reactions are favorable
