[en] During the grant period, 1994--97, the author continued to investigate the structure of few-electron atomic negative ions and the manner in which they interact with electromagnetic radiation. The experimental procedures and the results of this work have been described in detail in the published papers cited in Section G. Two complementary laser-ion beam apparatus were used in the measurements. A crossed beam apparatus, situated at Oak Ridge National Laboratory (ORNL), was used to perform a spectroscopic study of the electrons ejected, in the forward direction, from moving negative ions in the photodetachment process. In this work, the author isolated specific detachment channels by energy analyzing the electrons. The apparatus was used to investigate photodetachment of an electron from a negative ion in an excited state. The C^- ion is unusual in that it can be produced in a bound excited state as well as the ground state. The author also used this apparatus, with ba gaseous target replacing the laser beam, to study resonances in collisional detachment cross sections. In particular, he investigated the simplest of all shape resonances, the ³P^O state in Li^-. This state was produced in Li^--He collisions. A collinear beam apparatus, situated at Chalmers University of Technology (CUT) in Gothenburg, Sweden, has been used in spectroscopic studies of the He^- and Li^- ion in the ultraviolet. Here, the emphasis is on the production and detection of highly correlated, doubly excited states
