Within the Briggs perturbed united-atom (UA) model a simple cross section formula has been derived for ionisation of the 1s sigma molecular orbital (MO) to s continuum states from straight-line trajectories, in a form which exhibits the coherent contribution of both collision partners to this process. The corrections for Coulomb and relativistic effects as used in the present work preserve the structure of this formula. Interesting behaviour of the ionisation due to the target motion as a function of the target atomic number is predicted and explained by the relativistic contraction of the 1s sigma MO. By means of an approximate scaling law, the calculations are compared with 520 published experimental cross sections (30 |
