Abstract
The method of hidden crossings is generalized to treat multielectron s ystems utilizing molecular Hartree-Fock and configuration interaction methods, extended into the plane of complex internuclear distance. Dia batic promotion of low lying states to the continuum in a two-electron , two-center system via a series of localized transitions is shown for the first time. Excellent agreement with experiments is found regardi ng single ionization in 50 eV to 1 keV HCH collisions.
