Very brief summaries are given on three research topics. Electron impact elastic, excitation, and total cross sections for K were investigated by using elaborate Cl target wave functions in the close-coupling approximation. Photoionization cross sections from ground-state Na were calculated near the 2s{sup 2}2p{sup 5}3s and 2s2p{sup 6}3s inner-shell thresholds; also, the photoionization cross sections of excited 3p {sup 2}P{sup o} and 3d {sup 2}D states were calculated with the R-matrix methodology near the 2s2p{sup 6}3s thresholds. A numerical approach was developed to calculate the charge transfer matrix elements for ion-atom(ion) collisions; this was used for the proton-hydrogen collision problem as an illustration.
