Abstract
SynopsisThe 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.

Synopsis The B-spline R-matrix with pseudo-states method was employed to treat electron collisions with magnesium atoms
The purpose of the present work, is to provide a comprehensive set of results that covers essentially all recent experimental data. This systematic comparison of available experimental and theoretical results makes it possible to assess the accuracy of the existing data and to search for possible sources of the main discrepancies between experiment and theory
The largest scattering model included 712 coupled states, most of which were pseudo-states that simulate the effect of the highlying Rydberg continuum and, most importantly, the ionization continuum on the results for transitions between the discrete states of interest
Summary
Synopsis The B-spline R-matrix with pseudo-states method was employed to treat electron collisions with magnesium atoms. Electron scattering from magnesium has been intensively studied both experimentally and theoretically. Most previous calculations were devoted to selected individual transitions and a few energies (see [1] for references). The purpose of the present work, is to provide a comprehensive set of results that covers essentially all recent experimental data.
