Correlations in the ground-state wave function of Li-7

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