چکیده | ||
An analysis of selected fission fragment angular distributions from helium-ion induced fission is made using an exact theoretical expression. Theoretical anisotropies obtained with the transition state model are compared with their corresponding values deduced from the statistical scission model. The nuclear moment of inertia extracted from the model calculations are compared with their estimated values from a microscopic theory, which includes the nuclear pairing interaction [I]. Single particle levels of Nilsson eta!. are utilized. It is found that the value of the statistical parameter, Ko2(Ko2deff T/h2) is very sensitive to the energy gap parameter, A. The reduction of energy gap results in an increase in the moment of inertia. The effect of pairing interaction on the inertia parameters is illustrated and discussed | ||
