Correlations in the ground-state wave function of 7Li

Experimental momentum distributions for the transitions to the ground state and first excited state of 6He have been measured via the reaction 7Li(e, e'p)6He. They are compared to theoretical distributions calculated with mean-field wave functions and with variational Monte Carlo (VMC) wave functions which include strong state-dependent correlations in both 7Li and 6He. These parameter-free VMC calculations reproduce the measured data, including their normalization. This is the first successful comparison of experiment and ab initio theory for spectroscopic factors in 1p-shell nuclei
