Nuclear charge radii of Li9,11: The influence of halo neutrons
The nuclear charge radius of Li11 has been determined for the first time by high-precision laser spectroscopy. On-line measurements at TRIUMF-ISAC yielded a Li7-Li11 isotope shift (IS) of 25101.23(13) MHz for the Doppler-free 2s S1/22→3s S1/22 transition. IS accuracy for all other bound Li isotopes was also improved. Differences from calculated mass-based IS yield values for change in charge radius along the isotope chain. The charge radius decreases monotonically from Li6 to Li9, and then increases from 2.217(35) to 2.467(37) fm for Li11. This is compared to various models, and it is found that a combination of halo neutron correlation and intrinsic core excitation best reproduces the experimental results. © 2006 The American Physical Society.
