Show affiliationsA treatment of the heavy particle collision dynamics in a form of molecular orbital coupled channel approach, emerging from the hidden crossings topology of the complex adiabatic eigenenergy surface, is proposed. We show how this can be self-consistently adjusted for application in the nearly adiabatic limit of collision energies. The method is tested for the charge transfer process in He2++H collisions, in a range of 10–400 eV/u collision energies. Excellent agreement of the partial and total cross sections with other accurate theories and experiments is shown, and comparative advantages of the method are discussed.
