Ionization of Hydrogen and Hydrogenic Ions by Antiprotons [PDF]

Physical Review Letters, 1996
Presented here is a description of the ionization of hydrogen and hydrogenic ions by antiproton-impact, based on very large scale numerical solutions of the time-dependent Schrödinger equation in three spatial dimensions and on analysis of the topology of the electronic eigenenergy surfaces in the plane of complex internuclear distance.
