Abstract: Nuclear charge radii of Be-7,Be-9,Be-10,Be-11 have been determined by high-precision laser spectroscopy. On-line measurements were performed with collinear laser spectroscopy in the 2s(1/2)-> 2p(1/2) transition on a beam of Be+ ions. Collinear and anticollinear laser beams were used simultaneously, and the absolute frequency determination using a frequency comb yielded an accuracy in the isotope-shift measurements of about 1 MHz. Combining this with accurate calculations of the mass-dependent isotope shifts yields nuclear charge radii. The charge radius decreases from Be-7 to Be-10 and then increases for the halo nucleus Be-11. When comparing our results with predictions of ab initio nuclear-structure calculations we find good agreement. Additionally, the nuclear magnetic moment of Be-7 was determined to be -1.3995(5)mu(N) and that of Be-11 was confirmed with an accuracy similar to previous beta-NMR measurements.
