“…A common assumption in the calculation of the angular anisotropy of fission fragments using by the transition state model is that all pre-scission neutrons are emitted prior to reaching the saddle-point, since it is not straightforward to separate experimentally the contribution of neutrons being emitted before the saddle-point and those emitted between the saddle and the scission points [26][27][28][29][30][31][32][33][34][35]. It is well known that the standard saddle-point statistical model (SSPSM) has become the standard theory of fission fragment angular distributions and received great success since it was proposed.…”

Pre-saddle neutron multiplicity has been calculated for several fission reactions induced by heavy ions and light particles. Experimentally, it is impossible to determine the contribution of neutrons being emitted before the saddle point and those emitted between the saddle and the scission points.Determination of the pre-saddle neutron multiplicity in our research is based on the comparison between the experimental anisotropies and those predicted by the standard saddle-point statistical model. Analysis of the results shows that the pre-saddle neutron multiplicity depends on the fission barrier height and stability of the compound nucleus. In heavy ion induced fission, the number of pre-saddle neutrons decreases with increasing the excitation energy of the compound nucleus.A main cause of this behavior is due to a reduction in the ground state-to-saddle point transition time with increasing the excitation energy of the compound nucleus. Whereas in induced fission by light particles, the number of pre-saddle neutrons increases with increasing the excitation energy of the compound nucleus.
