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

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 16 O nucleus is of particular interest regarding the study of correlated behaviour. Various theoretical models exist which attempt to describe these reactions [6,7,8] and there have been numerous measurements of twonucleon knockout reactions using both real and virtual photons [9,10,11,12,13,14,15]. In [9] the results from the first measurement of the 16 O(e,e ′ pn) 14 N reaction were reported and compared with theory.…”

After recent improvements to the Pavia model of two-nucleon knockout from 16 O with electromagnetic probes the calculated cross sections are compared to experimental data from such reactions. Comparison with data from a measurement of the 16 O(e,e ′ pn) reaction show much better agreement between experiment and theory than was previously observed. In a comparison with recent data from a measurement of the 16 O(γ,pn) reaction the model over-predicts the measured cross section at low missing momentum.

“…The measurements of these cross sections have only become possible in recent years [7] by means of modern electron beam facilities. Studies with 16 O and 12 C targets have been carried out at the AmPS-facility at NIKHEF-Amsterdam [5][6][7][8][9], the MAMI-facility in Mainz [10][11][12] and the SAL in Saskatchewan [13]. These have inspired a number of recent theoretical investigations [14][15][16][17][18][19][20].…”

Effects of nuclear correlations on theO16(e,e′pN)reactions t

et al. 2004

View full text Add to dashboard Cite

Calculations of the 16 O͑e , eЈp N͒ cross sections to the ground state and first excited levels of the 14 C and 14 N nuclei are presented. The effects of nuclear fragmentation have been obtained in a self-consistent approach and are accounted for in the determination of the two-nucleon removal amplitudes. The Hilbert space is partitioned in order to compute the contribution of both long-and short-range effects in a separate way. Both the twoproton and the proton-neutron emission cross sections have been computed within the same model for the nuclear structure as well as the same treatment of the reaction mechanism, with the aim of better comparing the differences between the two physical processes. The 16 O͑e , eЈ pp͒ reaction is found to be sensitive to shortrange correlations, in agreement with previous results. The 16 O͑e , eЈ pn͒ cross section to 1 + final states is dominated by the ⌬ current and tensor correlations. For both reactions, the interplay between collective (long-range) effects and short-range and tensor correlations plays an important role. This suggests that the selectivity of ͑e , eЈpN͒ reactions to the final state can be used to probe correlations also beyond short-range effects.
