Single-nucleon spectroscopic overlaps from the ab initio symmetry-adapted no-core shell model*

Ab initio symmetry-adapted no-core shell model (SA-NCSM) calculations of single-nucleon spectroscopic observables are a first step to description of low-energy nuclear reactions and can be used as input for analyzing existing or future experimental data as well as for fitting ab-initio-based optical potentials. The SA-NCSM utilizes emergent symmetries in nuclei to reduce the dimensionality of the model space. This, in turn, allows one to reproduce the low-energy nuclear dynamics with only a small fraction of the model space, and hence making solutions to heavier nuclei and ultralarge model spaces feasible. This work discusses calculations of spectroscopic overlap functions, spectroscopic factors and asymptotic normalization coefficients (ANC’s) for Li isotopes.
