MEASUREMENT OF COMPLETE FUSION-FISSION AND TRANSFER-FISSION CROSS-SECTIONS AND ANGULAR-DISTRIBUTIONS FOR F-19-232 AT SUBBARRIER ENERGIES BYFISSION FRAGMENT FOLDING-ANGLE TECHNIQUE(TH)

Fission fragment folding-angle technique has been used to separate the complete fusion-fission (CFF) and the transfer-induced fission (TF) c omponents in the reaction of F-19 on Th-232 for the first time in sub- barrier energies. The fragment folding-angle distributions were measur ed using two position-sensitive Breskin-type detectors and were compar ed with simulations based on the kinematics for complete fusion-fissio n and transfer-fission events. The results on the excitation function and angular distributions for the CFF, TF and total fission events hav e been simultaneously measured over the bombarding energy range of 78. 5 MeV to 106.5 MeV for the above system.
