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.

Study of the (α, 2α) reaction
1982, Nuclear Physics, Section A
An alternate treatment for the distorted waves in the distorted wave impulse approximation (DWIA) formalism for the quasi-free (α, 2α) reaction is proposed. The prescription is based on the surface localization of this reaction. It describes the distorted waves directly in terms of the measured α-nucleus phase shifts. The predictions based on this formalism are compared with the available data at 140 MeV and 90 MeV on ¹⁶O, ²⁴Mg, ⁴⁰Ca and ⁶⁶Zn. They agree very well both in magnitude and shape.
On the final-state interactions in (e, e′p) reactions
1976, Nuclear Physics, Section A
Distorted momentum distributions in the ¹²C(e, e'p) reaction are calculated using the Elton-Swift wave functions for the bound-state protons. Final-state interactions between the ejected proton and residual nucleus are taken into account by means of the WKB approximation using the complex optical potential. It is shown that the factors governing qualitative features of the distorted momentum distributions are the angle ω between the recoil momentum vector and the vector k_p and the quantity $(E_{p} / k_{p}) \bar{Re V}$ , where (E_p, k_p) is the four-momentum of the ejected proton and $\bar{Re V}$ is some average value of the real part of the optical potential. Measurement of the distorted momentum distributions over a wide range of the angle ω is proposed.

Hole states in single-particle knock-out reactions
1973, Nuclear Physics, Section A
The hole states created in single-particle knock-out reactions are physical states but have finite lifetime. The hole is moving in a complex potential, the imaginary part of which is related to the width of the state, and the hole energy and wave functions are complex. The influence of these features on the momentum distributions of the hole is studied for the knock-out of the 1s and 1p protons from ¹²C and is found to be rather insignificant. However it is interesting to note that the overlap integral in momentum space shows a significant change.
