Fission fragment folding angle distribution for the ¹⁸O+²³²Th, ²⁰⁹Bi systems near the coulomb barrier energies

Study of heavy ion induced fission fragment angular distributions performed around the Coulomb barrier yield information about the fission dynamics. In the measurements of fission fragment angular anisotropy and the folding angle measurement of the ¹⁶O+²³²Th system, the fission events due to the low momentum transfer and the full momentum transfer were separated. The aim of the present experiment is to study the role of two neutrons in ¹⁸O in fission fragment folding angle distribution on ²³²Th target and compare it with the ¹⁶O induced fission on the ²³²Th with the similar excitation energy
