The objective of the research is the theoretical treatment of the formation and destruction of negative ions due to electromagnetic fields, the collisions of Rydberg atoms with ground state alkali-metal atoms and inelastic collisions of low energy electrons with molecules. Both stable and unstable negative ions will be investigated using integral equation techniques, semi-classical approaches and the Faddeev formulation. For the ab-initio electron-molecule calculations, the R-matrix method developed by Schneider and Burke, is invoked.
