摘要

Differential cross-sections for exclusive ~(16)O(e,e'pp)~(14)C processes are computed within a distorted-wave framework which includes central short-range correlations and intermediate Δ~+ excitations. The cross-sections are compared to high-resolution data from the MAMI facility at Mainz for a central energy and momentum transfer of = 215 MeV and = 316 MeV, respectively. A fair agreement between the numerical calculations and data is reached when using spectroscopic information extracted from a ~(15)N(d,~3H3)~(14)C experiment. The comparison between the calculations and the data provides additional evidence that short-range correlations exclusively affect nucleon pairs with a small center-of-mass momentum residing in a relative S state.
