DISSOCIATIVE EXCITATION OF CSII UPON E-CSF COLLISIONS

Inelastic collisions of electrons with cesium fluoride molecules were studied by means of the extended crossed beams technique. It was found that dissociation of CsF, ionization of the cesium atom, and excitati on of the atomic ion formed take place during a single collision. Diss ociative excitation cross sections for CsII spectral lines were measur ed. On the basis of these measurements, excitation cross sections for energy levels of single-charged cesium ion were calculated.
