Abstract:

We present a model to calculate cross sections for electroinduced two-nucleon emission from finite nuclei. Short-range correlations in the wave functions and meson-exchange contributions to the photoabsorption process are implemented. Effects of the short-range correlations are studied with the aid of a perturbation expansion method with various choices of the Jastrow correlation function. The model is used to investigate the relative importance of the different reaction mechanisms contributing to the A(e,e

'

pn) and A(e,e

'

pp) process. Representative examples for the target nuclei

~{12}

C and

~{16}

O and for kinematical conditions accessible with contemporary high-duty cycle electron accelerators are presented. A procedure is outlined to calculate the two-nucleon knockout contribution to the semi-exclusive (e,e

'

p) cross section. Using this technique we investigate in how far semi-exclusive (e,e

'

p) reactions can be used to detect high-momentum components in the nuclear spectral function.
