Charge radii and electromagnetic moments of Li and Be isotopes from the ab initio no-core shell model

Recently, charge radii and ground-state electromagnetic moments of Li and Be isotopes were measured precisely. We have performed large-scale ab initio no-core shell model calculations for these isotopes using high-precision nucleon-nucleon potentials. The isotopic trends of our computed charge radii and quadrupole and magnetic-dipole moments are in good agreement with experimental results with the exception of the Li-11 charge radius. The magnetic moments are in particular well described, whereas the absolute magnitudes of the quadrupole moments are about 10% too small. The small magnitude of the Li-6 quadrupole moment is reproduced, and with the CD-Bonn NN potential, also its correct sign.
