Abstract

The size dependence of the electron detachment process of negatively charged clusters was investigated. The electron binding energy was found to be the important parameter in the determination of both the threshold behavior and the magnitude of the cross section above threshold. It was found difficult to extend systematic sie-dependent studies of electron-anion collisions to very large clusters due to the limited magnetic rigidity of the heavy ion storage rings. The results suggest that the size-dependent polarizability of the clusters is responsible for the observed behavior.
