摘要：

The R-matrix method has been used to calculate electron impact excitation cross sections for the lowest seven electronically excited states of CO in the energy range 6-18 eV. These states are represented using configuration interaction (CI) expansions and an algorithm for treating long CI expansions in scattering calculations is presented. The calculations are carried out for a range of internuclear distances 1.8 less-than-or-equal-to R less-than-or-equal-to 3.0 a0. Several new resonance structures are identified. Good agreement is obtained with the recent experimental results of Furlong and Newell for the excitation of the a 3PI state.
