Abstract
With the goal of developing predictive ab initio capability for light and medium-mass nuclei, two-nucleon and three-nucleon forces from chiral effective field theory are optimized simultaneously to low-energy nucleon-nucleon scattering data, as well as binding energies and radii of few-nucleon systems and selected isotopes of carbon and oxygen. Coupled-cluster calculations based on this interaction, named , yield accurate binding energies and radii of nuclei up to , and are consistent with the empirical saturation point of symmetric nuclear matter. In addition, the low-lying collective states in and are described accurately, while spectra for selected - and -shell nuclei are in reasonable agreement with experiment.
