Analysis of 12C(p, 2p) and 12C(e, e′p) reactions at high energies

Abstract

The (p, 2p) reaction data at 460 MeV and 1 GeV incident proton energies and (e, e'p) data around 600 MeV incident electron energy on 12C nucleus have been analysed using the phenomenological Elton-Swift wave function and the projected Hartree-Fock (PHF) wave function for the bound proton. For the (p, 2p) reaction the distorted-wave impulse approximation (DWIA) has been used, while the (e, e'p) data are analysed using the McVoy and Van Hove form for the electron-proton interaction and distorted waves for the outgoing proton. It is found that the predicted cross section agrees with the experimental cross section for the (p, 2p) reaction at the two energies and with the cross section for the knock-out of a 1s proton in the (e, e'p) reaction. The computed 1p momentum distribution for the (e, e'p) reaction peaks at higher momentum than the corresponding experimental distribution.
