【 摘 要 】

We report on the progress towards measuring the charge radius of (sup 6)He and (sup 8)He nuclei by performing laser spectroscopy on these helium atoms in a magneto optical trap (MOT). First tests to produce neutral (sup 6)He atoms via the (sup 12)C((sup 7)Li, (sup 6)He)(sup 13)N reaction at the ATLAS accelerator have been successfully conducted. The MOT apparatus including the laser system and the discharge source to populate the metastable level are currently being set up.
