An ensemble‐average one‐electron potential is used to define a molecular orbital basis suitable for the simultaneous description of a set of low‐lying electronic states. The common basis simplifies the construction of the coupling between different Born‐Oppenheimer states, and the required matrix elements are calculated. A new excitation mechanism is developed for inelastic scattering of O + on Ne.
