【 摘 要 】

Synopsis The B-spline R-matrix with pseudo-states method was employed to treat electron collisions with magnesium atoms. Predictions for elastic scattering, excitation, and ionization (including ionization plus excitation) were obtained for all transitions between the lowest 25 states of magnesium. The accuracy of the predictions was checked by comparing with available experimental data and with results obtained in different approximations with increasing number of coupled states.
