Connecting Collisional and Photofragmentation Resonances in the H Ungerade Symmetry
Dávid Hvizdoš, Roman Čurík, Chris H. Greene
A recently developed energy-dependent frame transformation theory that incorporates both ionization and dissociation channels of the H molecule, is extended to treat the ungera…

Competing Ionization and Dissociation: Extension of the energy-dependent frame transformation to the gerade symmetry of H
David Hvizdos, Roman Curik, Chris H Greene
This article solves two major tasks that frequently arise in the theory of electron collisions with a target molecular cation. First, it extends the energy-dependent frame transfor…
