Quasi Free 238U (e,e'f)-Cross Section in Macroscopic-Microscopic Approach

We present the result of a theoretical study of inclusive quasi free electrofission of 238 U. The off-shell cross sections for the quasi free reaction stage have been calculated within the Plane Wave Impulse Approximation (PWIA), using a Macroscopic -Microscopic description of the proton and neutron single particle momentum distributions. Electron wave function distortion corrections were included using the effective momentum approximation, and the Final State Interaction (FSI) effects were calculated using an optical potential. The fissility for the proton single hole excited states of the residual nucleus 237 Pa was calculated both without and with contributions of the preequilibrium emission of the particles. The fissility for 237 , 238 U residual nuclei was calculated within the compound nucleus model. The ( e, e ′ f ) − cross sections thus obtained were compared with available experimental data.
