“…The value of β = 2⋅10 obtained from our analysis coincides with the value found in ref. [19] for the reaction Au (800⋅A MeV) + p. Other work [49,50,51] sensitive to the same deformation range is consistent with our conclusions, although often only upper limits for the transient time or the dissipation coefficient could be deduced.…”

Abstract:We examine the manifestation of transient effects in fission by analysing experimental data where fission is induced by peripheral heavy-ion collisions at relativistic energies. Available total nuclear fission cross sections of 238 U at 1⋅A GeV on gold and uranium targets are compared with a nuclear-reaction code, where transient effects in fission are modelled using different approximations to the numerical time-dependent fission-decay width: a new analytical description based on the solution of the Fokker-Planck equation and two widely used but less realistic descriptions, a step function and an exponential-like function. The experimental data are only reproduced when transient effects are considered. The deduced value of the dissipation strength β depends strongly on the approximation applied for the time-dependent fission-decay width and is estimated to be of the order of 2·10 21 s -1. A careful analysis sheds severe doubts on the use of the exponential-like in-growth function largely used in the past. Finally, we discuss which should be the characteristics of experimental observables to be most sensitive to transient effects in fission.
