Work on x-ray emission in heavy-ion collisions has concentrated on two general areas: (a) studies of fast electron rearrangement following multiple K plus L-shell ionization, and (b) environmental influences on x-ray emission from few-electron ions. With regard to the former topic, a study of fluorine K x-ray spectra excited by 5.5 MeV alpha particles in a series of alkali and alkaline earth fluorides was completed. This work resulted in the discovery of a resonant electron transfer mechanism associated with the formation of a molecule-ion between adjucent cation and anion sites. Concerning the second topic area, two projects were completed this year. The first involved high resolution K x-ray angular distribution measurements for H- and He- like sulfur and the other involved a study of dynamic screening energy shifts and collision broadening of 2p-1s transitions in 2-MeV/amu H- and He/sup -/ like Ne, Mg, and S ions. Manuscripts describing both of these projects are included in the appendix. Brief descriptions of the projects which are currently in progress are given. (WHK)
