%X The first-order effective charge description of the electron impact ionisation of H(ls) is considered. The effect of imposing the Peterkop relation on the charges occurring therein is discussed. A special case corresponding to high energy asymmetric geometry is considered and values for the effective charges deduced by comparison with the most accurate available theoretical and experimental data.
