Abstract
An analytic scattering model is applied to the problem of double‐curve crossings in predissociation. Analytic expressions are obtained for the energy shift ΔE and linewidth Γ by searching for poles in the scattering matrix. The validity of perturbation expressions for these parameters is examined by comparing numerical calculations of these expressions to our results. It is found that contributions from individual crossings are not always additive owing to interference effects.Keywords
