Title of program: BETRT
Catalogue Id: AAXK_v1_0
Nature of problem
The calculation of cross sections for electron impact excitation of neutrals in the intermediate energy range is greatly complicated by the large number of partial waves which contribute. It has been argued that the unitarised Born approximation gives an adequate representation of all but the partial cross sections corresponding to the smallest values of L, the total angular momentum. Further for L large the Born Reactance matrix may be approximated to a high degree of accuracy by the Bethe. The ...
