MASS-DISTRIBUTION IN O-16-INDUCED FISSION OF TH-232

The recoil catcher technique and gamma spectrometry of fission product s were used to determine the cumulative/independent cross-sections of 18 fission products in 92 and 105 MeV O-16-induced fission of Th-232. The charge distribution parameters were obtained from the best fit of the mass distribution. At both energies the mass distributions are sin gle peaked Gaussian. The fission cross-sections at 92 and 105 MeV are 386 +/- 35 and 595 +/- 48 mb and the total number of neutrons emitted per fission 8.4 +/- 1.4 and 10.2 +/- 1.6 respectively.
