Experimental momentum distributions for the transitions to the ground state and first excited state of 6 He have been measured via the reaction 7 Li͑e, e 0 p͒ 6 He. They are compared to theoretical distributions calculated with variational Monte Carlo (VMC) wave functions which include strong state-dependent correlations in both 7 Li and 6 He. These VMC calculations provide a parameter-free prediction that reproduces the measured data, including its normalization. The deduced spectroscopic factor for the two transitions is 0.58 6 0.05, in perfect agreement with the VMC value of 0.60. This is the first successful comparison of experiment and ab initio theory for spectroscopic factors in p-shell nuclei.
