N2 - A method of selective suppression of negative ions by electron photodetachment with a laser beam is investigated. The interaction of 532 nm photons from a Nd:YAG laser with negative ions of 32S, 37Cl and 40Ca16O was studied. A strong depletion of 32S- and 40Ca16O- beam intensities, but no effect on 37Cl- ions, was observed. Photodetachment cross sections of (1.0±0.2)×10-17 cm2 and (7±3)×10-17 cm2 were measured for 32S- and 40Ca16O-, respectively. Implications for accelerator mass spectrometry measurements are discussed.
