3 Feb 2000 | | Journal: | Phys.Rev. C61 (2000) 054617 | | Subject: | nucl-th | | Affiliation: | U. of Pavia, Italy | | Abstract: | The general formalism of nucleon recoil polarization in the (${vec e},e’{vec N}N$) reaction is given. Numerical predictions are presented for the components of the outgoing proton polarization and of the polarization transfer coefficient in the specific case of the exclusive $^{16}$O(${vec e},e’{vec p}p$)$^{14}$C knockout reaction leading to discrete states in the residual nucleus. Reaction calculations are performed in a direct knockout framework where final-state interactions and one-body and two-body currents are included. The two-nucleon overlap integrals are obtained from a calculation of the two-proton spectral function of $^{16}$O where long-range and short-range correlations are consistently included. The comparison of results obtained in different kinematics confirms that resolution of different final states in the $^{16}$O(${vec e},e’{vec p}p$)$^{14}$C reaction may act as a filter to disentangle and separately investigate the reaction processes due to short-range correlations and two-body currents and indicates that measurements of the components of the outgoing proton polarization may offer good opportunities to study short-range correlations. | | Source: | arXiv, nucl-th/0002012 | | Services: | Forum | Review | PDF | Favorites | |
