Abstract [en]

Electronic coupling of two or more resonances via the electron scattering continuum is investigated. The effect of this coupling as a function of the resonance curves and autoionization widths is investigated, and the conditions for the maximum effect are determined. The theory is applied to two physical problems, the product state distribution produced by the dissociative recombination of electrons with HeH+ and a one-dimensional model for ion-pair production resulting from electron collisions with H-3(+). It is found that the coupling does not affect the product state distribution in HeH+ but produces a significant effect in the H-3(+) model.
