Description
The shadow effect in the angular distributions of fission fragments is observed and shadow minima are quantitatively studied in experiments with the monocrystalline UO2 target exposed to 3He ions at 25, 31, 40, 47 MeV. Measured values of the difference of the shadow yields at the minima Δsub(chi) show a significant time duration of the fission events which exceeds the result of the model calculation taking into account many chances of fission after the neutron emission. Peculiarities of the behaviour of the compound-nucleus lifetime as a function of the excitation energy are discussed
