Abstract
Pre-scission neutron multiplicities from fission of the compound nuclei ${}^{210,212,214,216}$Rn have been measured in order to investigate the $N/Z$ dependence of fission hindrance. The Rn isotopes are populated through the fusion of ${}^{16,18}$O $+$ ${}^{194,198}$Pt systems and are formed at four excitation energies in the range of 50--79 MeV. The experimental pre-scission neutron yield is compared with predictions from the statistical model of compound nuclear decay containing the strength of nuclear dissipation as a free parameter. The strength of nuclear dissipation obtained in the present analysis does not show any specific dependence on the $N/Z$ values of the fissioning nuclei at large excitation energies. The dissipation strength at the lowest excitation energy, however, indicates a shell closure effect at $N=126$ for the ${}^{212}$Rn isotope.
