The multiplicities, angular correlations, and energy spectra of the neutrons associated with fission were measured for the reactions of 25,26Mg + 238U and 248Cm. From these data, we extracted a value of Gn/Gf for the first-chance fission of 264Rf and 274Hs at an excitationenergy of 60 MeV. The implications of this result for understanding the survival probabilities of excited heavy nuclei formed in �hot� fusion reactions are discussed.
