Fission fragment angular distributions and the electrofission cross section of 2 3 2 Th were measured in the electron energy region 4.5-7.9 MeV. Below 5.20 MeV two distinct shelves were observed in the isotropic component of the total electrofission cross section, indicating the presence of resonances in the photofission cross section at 4.55 [(2 + , 0) channel] and at 4.95 MeV [(1 - , 0) channel]. These resonances are interpreted as associated to vibrational levels in the second well of the 2 3 2 Th fission barrier. Moreover, a resonance observed at 5.65 MeV in both channels is interpreted as a signature for a vibrational level in the third well of the triple-humped fission barrier deduced for this nucleus.
