Abstract
The rotational excitation of CN by proton impact is studied using the decoupled l-dominant (DLD) method. When compared with the results of exact quantum close-coupling calculations, the DLD method is seen to offer a considerable reduction in computer time as well as a reasonable degree of accuracy, especially at high collision energies. Additionally, the method is considerably more accurate than the Born approximation and does not require the arbitrary Born cut-off factors.Keywords
