Abstract
Using a diagonalized form of the interaction matrix in electron-atom scattering problem (adiabatic representation) , some excitation and spin-change processes are calculated in e-H and e-He collisions. The configuration mixing of the diabatic states, allowing for the correlation effects in the system, is shown to be a significant factor in determining the near threshold behaviour of the inelastic cross section. The calculations demonstrate the superiority of the adiabatical representation in respect to the Bornmethod even in the first order of the theory. The results are compared with the more elaborate calculations in the Veinshtein and close-coupling methods as well as with the experimental data.
