Abstract:

This research involves experimental studies of compound states of negative ions using laser beams. Negative ion beams of stable H-, O-, etc. and metastable He-, Be-, Ca-, etc. species are generated by double charge exchange from positive ion beams colliding with alkali vapor. Measurements of the photodetachment and autodetachment spectra for these ions provide new information on compound state energy levels. In addition experiments are underway to study the collisions of electrons with atoms in strong laser fields. Many theoretical predictions have been presented recently on this subject. These experiments should provide the first tests of such predictions.
