Abstract
Excitation functions for xn-evaporation channels of the Ne-22+Pt-194,P t-196,Pt-198 reactions have been measured in the compound nucleus exci tation energy range of 45-110 MeV. The Gamma(n)/Gamma(tot) = 0.88 +/- 0.07 was obtained ill the range of the excitation energy of 60-100 MeV from the analysis of the ratios of the formation cross sections for t he same nuclides produced in reactions with different numbers of evapo rated neutrons. From this value of Gamma(n)/Gamma(tot) the fission tim e of (3-5). 10(-20) s is derived for the compound nuclei.
