Nuclear Charge Radii of Be-7,Be-9,Be-10 and the One-Neutron Halo Nucleus Be-11 KU Leuven
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.
