GFMC calculations of one-nucleon overlaps and spectroscopic factors in light nuclei*

We present one-nucleon overlap functions for light $(A \le 10)$ nuclei computed from ab-initio Green's function Monte Carlo wave functions. The wave functions are based on realistic two- and three-nucleon Av18+IL7 interactions. Our overlap functions extend into long-range regions with correct asymptotics. The overlap functions are used to obtain spectroscopic factors and can serve as an input for low-energy reaction calculations.
