【 摘 要 】

The B-spline R-matrix-with-pseudostates (BSR) method is employed to treat electron collisions with beryllium atoms. Predictions for elastic scattering, excitation, and ionization are presented for all transitions between the lowest 19 states of beryllium in the energy range from threshold to 150 eV. The sensitivity of the results is checked by comparing data obtained in different approximations with increasing number of pseudo-states.
