Abstract
In this article some of our recent results on fission fragment /product angular distributions are discussed in the context of noncompound nucleus fission Measurement of fission fragment angular distribution in 28Si +176Yb reaction did not show a large contribution from the noncompound nucleus fission Data on the evaporation residue crosssections in addition to those on mass and angular distributions are necessary for better understanding of the contribution from noncompound nucleus fission in the preactinide region Measurement of massresolved angular distribution of fission products in 20Ne +232Th reaction showed an increase in angular anisotropy with decreasing asymmetry of mass division This observation can be explained based on the contribution from preequilibrium fission Results of these studies showed that the mass dependence of anisotropy may possibly be used to distinguish preequilibrium fission and quasifission
