This is a database of electron impact excitation and ionization cross sections and rate coefficients calculated by the complex of programs ATOM-AKM. Currently it contains data for H, He, Li, Be and Be+. The excitation cross sections are computed for transitions among SL terms of a certain set of electronic configurations. Calculation procedure is based on K-matrix method which allows to improve Born results, in particular to include the effects of normalization, excitation via intermediate states and the interaction between channels. The ionization cross sections are calculated in the Born approximation with normalization.
