Abstract

The necessity of including the interchannel coupling in the calculation of low-energy associative electron detachment (AD) collisions was addressed. In additional experiments, the electron spectra at increased collision energies were studied. As expected, the rovibrational onsets are shifted towards higher electron energies with rising collision energy. Nonlocal resonance theory predicted that the nonlocal steps S_v remain essentially unshifted.
