  We investigate the properties of 7Li with the JISP16 and chiral NNLO_opt
nucleon-nucleon interactions and 7Be with the JISP16 interaction in the ab
initio no-core full configuration (NCFC) 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.
