    • Abstract


      The role of the electronic kinetic energy and its Cartesian components is examined during the formation of the ground (1Σ), the first excited (1Σ)* and the lowest (3Σ) states of HeH+ employing wavefunctions of the multi-configuration type with, basis orbitals in elliptic coordinates. Results show, contrary to earlier beliefs, that the bond formation in these states is preceded primarily by a charge transfer from the neutral atom to the ion. There is no evidence of polarisation of the neutral atom orbitals by the ion even at large internuclear separation.
