The recoil catcher technique and gamma spectrometric assay of fission products were used to measure angular distribution of 17 fission products in [sup 10]B, [sup 12]C, and [sup 16]O induced fission of [sup 232]Th at near barrier energies. The observed mass dependence of anisotropies of fission products in these systems are very different from that of [ital p] and [alpha] induced fission of [sup 232]Th at similar excitation energies. It has been suggested that the difference in the rotational energy for the symmetric and asymmetric modes for large compound nucleus spins could be responsible for the observed variation. No systematic change in the mass dependence of anisotropies across the Bussinaro-Gallone point was observed. For [sup 16]O induced fission of [sup 232]Th, sharp variation in anisotropies have been observed in the mass region 120--135. This has been attributed to transfer induced fission.
