The 16 O(e,e‘pp)14 C reaction to discrete final states

Abstract

This paper reports on the first measurement of the 16 O(e,e ′ pn) 14 N reaction. Data were measured in kinematics centred on a super-parallel geometry at energy and momentum transfers of 215 MeV and 316 MeV/c. The experimental resolution was sufficient to distinguish groups of states in the residual nucleus but not good enough to separate individual states. The data show a strong dependence on missing momentum and this dependence appears to be different for two groups of states in the residual nucleus. Theoretical calculations of the reaction using the Pavia code do not reproduce the shape or the magnitude of the data.

“…The adopted correlation function provides a favorable agreement with the 12 C(e, e ′ pp) and 16 O(e, e ′ pp) data [53]. In the process of computing the Dirac-Glauber phase of Eq.…”

First measurements of the 16O(e, e'pn)14N reaction

“…These measurements were carried out in super-parallel kinematics and various low-lying states in 14 C were populated. Comparison with theoretical calculations [24] provided evidence that SRC affect nucleon pairs with small centre-of-mass momentum in relative S-states.…”

Quantifying short-range correlations in nuclei

“…There are experimental results supporting this conjecture. First, in high-resolution 16 O(e, e pp) 14 N measurements performed at the electron accelerators in Amsterdam [38] and Mainz [39], the quantum numbers of the target nucleus and the residual nucleus are unambiguously determined. For the transitions to low-lying states in the residual nucleus, the eightfold differential cross section for the exclusive (e, e pp) reaction has been studied as a function of the initial c.m.…”
