Abstract
We investigate the factorization properties of the exclusive electroinduced two-nucleon knockout reaction A(e,e′pN). A factorized expression for the cross section is derived and the conditions for factorization are studied. The A(e,e′pN) cross section is shown to be proportional to the conditional center-of-mass (c.m.) momentum distribution for close-proximity pairs in a state with zero relative orbital momentum and zero radial quantum number. The width of this conditional c.m. momentum distribution is larger than the one corresponding with the full c.m. momentum distribution. It is shown that the final-state interactions (FSIs) only moderately affect the shape of the factorization function for the A(e,e′pN) cross sections. Another prediction of the proposed factorization is that the mass dependence of the A(e,e′pp) [A(e,e′pn)] cross sections is much softer than Z(Z−1)/2 [NZ].
