| description | The number of neutrons emitted by compound nucleus before reaching the saddle-point ( ν pre) is calculated for 16 8 O+20882Pb , 12 6 C+23692U , 11 5 B+23793Np and 18 8 O+19779Au , h eavy-ion induced fission reaction systems. The behavior of angular anisotropies of fission fragments is normal for 16 8 O+20882Pb and 18 8 O+19779Au reaction systems, since the targets have spherical shapes. For these systems, the agreement between the angular anisotropies experimental data, as well as the predictions of standard saddle-point statistical model is high. And as the mass asymmetry, parameters is greater than the Businaro-Gallone asymmetry parameters α BG for the other two systems, the behavior of angular anisotropies of fission fragments is expected to be normal. Overall, an anomalous behavior in the angular anisotropies for these systems and the contributions of non compound nucleus events are observed. |
