Photon collisions with atoms and ions within an intermediate-energy R-matrix framework
Abstract
Recent experimental advances in light technology necessitate the availability of sophisticated theoretical models which can incorporate an accurate treatment of double-electron continua. We describe here an intermediate-energy R-matrix approach to photoionization and photo-double-ionization and illustrate its feasibility by application to photoionization and photo-double-ionization of He and photodetachment and photo-double-detachment of H-. Results are shown to be in excellent agreement with previous theoretical and experimental studies. This work is a key step in the development of a multipurpose R-matrix code for multiple-electron ejection.
