ABSTRACT

This paper reports a summary of the experimental results on pre- and post-scission neutron multiplicities (Mpre and Mpost) from 192;202Po compound nuclei populated by 48Ti+144,154Sm systems at 72 MeV excitation energy, studied using the National Array of Neutron Detectors (NAND) at IUAC, New Delhi. The experimental neutron yields along with already existing data for 12C+194Pt and 18O+192Os are compared with predictions from the statistical model of compound nuclear decay including the strength of nuclear dissipation as a free parameter. Mpre values obtained from the present analysis do not show any specific dependence on the (N − Z)=A values of the fissioning nuclei. In order to explain the experimental neutron multiplicities, the entrance channel effects are important.
