Connecting Collisional and Photofragmentation Resonances in the H2 Ungerade Symmetry
Abstract
A recently developed energy-dependent frame transformation theory that incorporates both ionization and dissociation channels of the H2 molecule, is extended to treat the ungerade states that occur both in dissociative recombination and as the final state in ground state photoabsorption. The theoretical treatment includes the rotational degrees of freedom and is benchmarked against a two-dimensional model that can be solved with high accuracy and also compared with photoabsorption experiments. Analysis of the resulting spectra shows how the same resonances appear in very different observables, often with quite different line shapes.
