摘要：

The total cross sections for electron and positron collisions with sodium and potassium are calculated in the modified Glauber (MG) approximations, employing the Szazs-McGinn wavefunctions within the frozen-core approach. While the present values of total cross sections for electron and positron collisions are found to be consistent with those previously obtained in the model-potential approach, the positron and electron MG cross sections of the present calculation merge with each other at a rather low energy, as was observed in experiments by Stein et al.
