Here we investigate the properties of 7Li with the JISP16 and chiral NNLOopt at next-to-next-to-leading order (NNLO) nucleon-nucleon interactions and 7Be with the JISP16 interaction in the ab initio no-core full configuration approach. We calculate selected observables that include energy spectra, point proton root-mean-square radii, electromagnetic moments, and transitions. We compare our results with experimental results, where available, as well as with results obtained using nucleon-nucleon plus three-nucleon interactions. We obtain reasonable agreement between theory and experiment for low-lying states that are dominated by p-shell configurations.
