Pre-scission particle and gamma-ray emission in heavy-ion-induced fission
An introduction is given to the physics of the equilibrium transition-state model and of dissipative nuclear dynamics. Experimental data on pre-scission particle and gamma-ray emission and their interpretation are reviewed. They appear to indicate overdamped motion of the nuclear fluid. A time scale for compound-nucleus fission of about 30 × 10−21 s or greater is indicated, whilst that for quasi- or fast-fission is somewhat shorter.
