Abstract
A systematic study of the electron impact excitation of lithium, sodium and potassium from their ground states is considered in distorted-wave approximation theory. Results for differential and integrated cross sections, alignment, orientation and spin asymmetry parameters in the energy range 10 - 100 eV are calculated and presented. Our integrated cross section results show good agreement when compared with other theories and available experiments. Present differential cross section results for sodium are also compared with the only available recent differential cross section measurements. For the sake of further meaningful comparison and discussions, the first Born calculations for the cross sections are also performed and compared.
