Quasi-free 238U(e,e′f) cross section in macroscopic–microscopic approach Original Research Article

We present the result of a theoretical study of inclusive quasi-free electrofission of 238U. 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. The fissility for the proton single hole excited states of the residual nucleus 237Pa was calculated both with and without contributions of the pre-equilibrium emission of the particles. The fissility of the 237,238U residual nuclei was calculated within the compound nucleus model. Final state interaction correction to the fissility was calculated using a pure imaginary optical potential. The (e,e′f) cross sections, thus obtained, were compared with available experimental data.
