Phys. Rev. Lett. 101, 032702 (2008) [4 pages]Fission Decay Widths for Heavy-Ion Fusion-Fission ReactionsReceived 30 January 2008; published 17 July 2008 Cross-section and neutron-emission data from heavy-ion fusion-fission reactions are consistent with a Kramers-modified statistical model which takes into account the collective motion of the system about the ground state, the temperature dependence of the location of fission transition points, and the orientation degree of freedom. The strong increase in the nuclear viscosity above a temperature of ∼1 MeV deduced by others is an artifact generated by an inadequate fission model. © 2008 The American Physical Society URL:
