The main focus of our project is electron correlation in atoms using methods based on hyperspherical coordinates. Our aim is primarily to lay the ground work for state-of-the-art calculations employing hyperspherical coordinates. In addition, we intend to make applications to specific atomic collision processes in those cases where a hyperspherical coordinate point of view can make a significant contribution to our understanding of the physical mechanisms involved. Brief descriptions are given for the following investigations: (1) asymptotic solution of the adiabatic hyperspherical equation, (2) pseudo-states in the adiabatic approximation, (3) determination of target average excitation energy from doubly differential electron-detachment cross section measurements, and (4) contribution of H* (n = 2 states to H/sup -/-He detachment collision cross sections. 9 refs., 1 figs.
