Computation of spectroscopic factors with the coupled-cluster method. Jensen, Hagen, G., Papenbrock, T., Dean, D. J., & Vaagen, J. S. *Physical Review C - Nuclear Physics*, 2010. doi abstract bibtex We present a calculation of spectroscopic factors within coupled-cluster theory. Our derivation of algebraic equations for the one-body overlap functions are based on coupled-cluster equation-of-motion solutions for the ground and excited states of the doubly magic nucleus with mass number A and the odd-mass neighbor with mass A-1. As a proof-of-principle calculation, we consider O16 as well as the odd neighbors O15 and N15 and compute the spectroscopic factor for nucleon removal from O16. We employ a renormalized low-momentum interaction of the Vlow-k type derived from a chiral interaction at next-to-next-to-next-to- leading order. We study the sensitivity of our results by variation of the momentum cutoff and then discuss the treatment of the center of mass. \textcopyright 2010 The American Physical Society.
