The cumulative yields of various fission products within the 77–153 mass regions in the 2.5-GeV bremsstrahlung-induced fission of ²³²Th have been determined by using the recoil catcher and an off-line γ -ray spectrometric technique at the Pohang Accelerator Laboratory, Korea. Themass-yield distributions were obtained from the cumulative yields after charge-distribution corrections. The peak-to-valley (P/V) ratio, the average value of light mass (‹AL›) and heavymass (‹AH›), and the average postfission number of neutrons (‹v›_expt) were obtained from the mass yield of the ²³²Th(γ, f ) reaction. The present and literature data in the ²³²Th(γ, f ) reaction were compared with the similar data in the ²³⁸U(γ, f ) reaction at various excitation energies to examine the role of potential energy surface and the effect of standard I and standard II asymmetric modes of fission. It was found that (i) even at the bremsstrahlung end-point energy of 2.5 GeV, the mass-yield distribution in the ²³²Th(γ, f ) reaction is triple humped, unlike ²³⁸U(γ, f ) reaction, where it is double humped. (ii) The peak-to-valley (P/V) ratio decreases with the increase of excitation energies. However, the P/V ratio of the ²³²Th(γ, f ) reaction is always lower than that of the ²³⁸U(γ, f ) reaction due to the presence of a third peak in the former. (iii) In both the ²³²Th(γ, f ) and ²³⁸U(γ, f ) reactions, the nuclear structure effect almost vanishes at the bremsstrahlung end-point energies of 2.5–3.5 GeV.
