The results of close-coupling calculations using the complex Kohn variational method are reported for a variety of low-energy electron-collision processes involving molecular chlorine. We report cross sections for elastic scattering and momentum transfer, as well as dissociative excitation of the five lowest electronically excited states ([sup 1,3][Pi][sub [ital u]], [sup 1,3][Pi][sub [ital g]], [sup 3][Sigma][sub [ital u]][sup +]) which are formed by promoting an occupied valence electron into an antibonding (5[sigma][sub [ital u]]) orbital. We also report cross sections for the excitation of the lowest bound optically allowed states in Cl[sub 2]. The cross sections, especially at very low energies, are found to depend sensitively on both target polarization and a proper balance of correlation effects in the [ital N]- and ([ital N]+1)-electron systems. Comparison is made between the results of this study and the limited body of experimental results available for this system.
