Experimental momentum distributions for the transitions to the ground state and first excited state of have been measured via the reaction . They are compared to theoretical distributions calculated with variational Monte Carlo (VMC) wave functions which include strong state-dependent correlations in both and . 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 , 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 -shell nuclei.
