Electron Impact

Integral cross-sections, differential cross-sections, alignment and lambda parameters for electron-impact excitation of the lowest autoionizing states of Li, Na and K have been calculated using Distorted-Wave method. We have applied a linear combination of static potentials of initial and final target states as the final channel distortion potential and the static potential of the initial target state as the initial channel distortion potential. The wave functions used in this model are the multi zeta and the double zeta Hartree-Fock single electron wave functions. Numerical calculations have been performed using a modified program. The results of this study are compared with experimental and theoretical data available in literature.
