R matrix calculations of the electron impact excitation cross sections for Cd+ ions

Systematic calculations of excitation cross sections o cadmium ion by low-energy electrons were made in the framework of R-matrix method. Collision forces were calculated in the approximation of a strong bond between the channels, bearing in mind 15 terms of 4d105s-, 5p-, 6s-, 5d-, 6p-, 4d95s2-, 5s5p-configurations in LS-bond. Special attention was paid to accurate presentation of the target wave functions in the framework of the Hartree-Fock multi-configuration method. The cross sections calculated manifest a clearly pronounced resonance structure, which makes a noticeable contribution into full excitation cross sections, especially for 4d105s-4d95s2-transition. Comparison with the known literature data was made
