CROSS-SECTIONS OF DISSOCIATIVE EXCITATION OF RUBIDIUM IN E-RBF COLLISIONS

Dissociative excitation of the rubidium atom and the single-charged ru bidium ion during collisions of slow electrons with RbF molecules was studied. It was found that dissociative excitation cross sections in t he spectral series of the rubidium atom obey the power law with the la rgest and smallest power index observed in the P-series and D-series, respectively. The contribution of the cascade population of the 5p lev els to the excitation cross sections of the single-charged rubidium io n was determined, and the cross sections for direct excitation of thes e energy levels were calculated.
