Proton-Induced Fission of ²³²Th at Low and Intermediate Energies

NUCLEAR REACTIONS ²³²Th(p, f), E=7-55 MeV; measured fission fragments mass distribution (yield), energy (TKE) at K-130 cyclotron at Jyvaskyla with fission fragments ToF measured by CORSET spectrometer at 13-55 MeV and at U-150M cyclotron at Almaty at 7, 10, 13 MeV; deduced symmetric and asymmetric fission modes in mass-energy distributions at all energies with yield of symmetric products falling with increasing proton energy, deduced indication of superasymmetric fission mode associated with increased yield of fragments with masses in region of A≈70; compared with published mass distributions from ²³⁵U, ²³⁹Pu, ²⁴²Am, ²⁴⁵Cm, ²⁴⁹Cf(n, f), E=thermal.
