We perform no-core configuration interaction calculations for nuclei in the p-shell. We show that for typical light nuclei, a truncation on the total number of quanta in the many-body system converges much more rapidly than a full configuration interaction (FCI) truncation, which is a truncation on the single-particle basis space. We present new results for the ground state energies of the Be isotopes with the nonlocal two-body potential JISP16, and discuss emerging phenomena such as clustering and rotational band structures in ⁹Be. We also show that the anomalously suppressed beta decay of ¹⁴C to the ground state of ¹⁴N can be reproduced using two- and three-nucleon forces from chiral effective field theory. In particular the structure of the ground state of ¹⁴N is sensitive to the three-nucleon force.
