We investigate properties of A=10 nuclei in the ab initio, no-core shell model using realistic Argonne and CD-Bonn nucleon-nucleon (NN) potentials and basis spaces through 9ħΩ (with basis dimensions reaching 5.5×108). Results for binding energies, excitation spectra (including negative parity and 2ħΩ-dominated intruder states), electromagnetic properties, and the isospin-mixing correction of the 10C⃗10B Fermi transition are presented. For 10B, these NN potentials produce a JπT=1+0 ground state, contrary to the experimental 3+0, a clear indication of the need for true three-body forces.
