Description
The multiplicities, angular correlations, and energy spectra of the neutrons associated with fission were measured for the reactions of 25,26Mg+232Th at 25Mg and 26Mg projectile energies of 132 and 148 MeV, respectively. From these data, we extracted a value of Γn/Γf for the first-chance fission of 258No at an excitation energy of 61 MeV. The implications of this result for understanding the survival probabilities of excited heavy nuclei formed in ''hot'' fusion reactions are discussed.
