Neutron multiplicity excitation function has been measured for the ^{30}\mathrm{Si}+^{197}\mathrm{Au}reaction populating the ^{227}\mathrm{Np}compound nucleus at excitation energies in the range 44.1--78.8 MeV using the National Array of Neutron Detector facility of Inter University Accelerator Centre, New Delhi. Measured pre-scission neutron multiplicity values are analyzed using a statistical model incorporating Krammer's fission width...
