  The large body of experimental data on the fission fragments anisotropies are
analyzed in several heavy-ion induced fission reaction systems. The entrance
channel mass asymmetry parameters of these systems put on the both sides of the
Businaro-Gallone mass asymmetry parameters. The role of the mass numbers of the
projectile and the target in the prediction of a normal or an anomalous
behavior in angular anisotropy, as well as the validity of standard
saddle-point statistical model are considered. The average contribution of non
compound nucleus fission for the systems with an anomalous behavior in
anisotropy are also determined. PACS numbers: 25.70.Jj *Corresponding author:
