“…For the AV18/UIX model, the GFMC energy for the 7 Li ground state is -37.4(3) MeV, where the number in parentheses is the statistical error due to the Monte Carlo energy evaluation. The 6 He(0 + ) ground state is at -27.6(1) MeV and the 6 He(2 + ) excited state is at -25.8 (2) MeV. While these ab initio energies are about 5% above experiment (which we attribute to inadequacies of the AV18/UIX model) the relative excitations of 9.8(3) and 11.6(3) MeV are fairly close to experiment.…”

“…PACS numbers: 21.10.Jx, 21.60.Ka, 25.30.Dh,27.20.+n In this letter we present new experimental data on the reaction 7 Li(e, e ′ p) 6 He and compare the deduced momentum distributions with recent ab initio predictions from variational Monte Carlo (VMC) calculations. Some years ago, two of us (Lapikás and Wesseling) participated in electron scattering experiments to determine shell occupancies in the nuclei 30 Si, 31 P, and 32 S [1,2]. In the latter case, a Li 2 S target was used, with resolution sufficient to separate the discrete transitions in the reaction 32 S(e, e ′ p) 31 P from those in the reaction 7 Li(e, e ′ p) 6 He.…”

“…The experiment was performed with the 1% duty factor electron beam from the NIKHEF mediumenergy accelerator (MEA) and the high-resolution twospectrometer setup in the EMIN end station [33]. The data were taken concurrently with those for the reaction 32 S(e, e ′ p) [1,2] for which purpose a self-supporting disc of Li 2 S was used as a target (thickness roughly 25 mg/cm 2 ). The target could withstand maximum average currents of 6 µA when rotated continuously.…”

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

“…Further evidence of the effects of correlated two-nucleon behaviour comes from measurements of spectroscopic strengths for the knockout of protons from nuclei with A > 4 [3,4,5]. The average value of the measured spectroscopic strength for a range of nuclei was found to be ≈ 65 % of that predicted by independent particle models.…”
