摘要
We have studied the excitation of atomic hydrogen by fully-stripped lithium ion impact in the intermediate energy range using a new and efficient implementation of the two-center atomic orbital approach with Gaussian-type orbitals. Partial and state-selective cross sections have been obtained for excitation up to H(6 h). A careful investigation of the convergence of the results with respect to the basis set has been performed which allows us to estimate the accuracy of the cross sections. Furthermore, our calculations provide an explanation for the discrepancies between previous calculations on this collision system.
