Query: Measurement of the Survival Probabilities for Hot Fusion Reactions   We have studied the fission-neutron emission competition in highly excited
$^{274}$Hs (Z=108) (where the fission barrier is due to shell effects) formed
by a hot fusion reaction. Matching cross bombardments ($^{26}$Mg + $^{248}$Cm
and $^{25}$Mg + $^{248}$Cm) were used to identify the properties of first
chance fission of $^{274}$Hs. A Harding-Farley analysis of the fission neutrons
emitted in the $^{25,26}$Mg + $^{248}$Cm was performed to identify the pre- and
post-scission components of the neutron multiplicities in each system.
($\Gamma$$_{n}$/$\Gamma$$_{t}$) for the first chance fission of $^{274}$Hs
(E$^{\ast}$ = 63 MeV) is 0.89 $\pm$ 0.13, i.e., $\sim$ 90 $%$ of the highly
excited nuclei survive.The high value of that survival probability is due to
dissipative effects during de-excitation. A proper description of the survival
probabilities of excited superheavy nuclei formed in hot fusion reactions
requires consideration of both dynamic and static (shell-related) effects.
