During the present grant period we have continued our study of the photodetachment of atomic negative ions using cross-beam photoelectron detachment spectroscopy. This technique involves the measurement of energies, yields and angular distributions of photoelectrons ejected from the interaction region between perpendicularly crossed laser and negative ion beams. Both structural and collisional properties of the negative ions are determined from the measured quantities. Measurements of the kinetic energies of the photoelectrons, for example, permits determinations of electron affinities of the parent atoms, whereas combined photoelectron yield and angular distribution measurements allow differential and angle-integrated photodetachment cross sections to be evaluated. 7 figs.
