Dissociative excitation of the singly charged lead ion in electron collisions with PbCl2 molecules

Inelastic collisions of slow electrons with lead dichloride molecules yield ing excited lead ions in a single encounter event were studied by the exten ded crossed-beam technique. At an incident electron energy of 100 eV, 67 cr oss sections for dissociative excitation of PbII spectral lines were measur ed. Three optical excitation Functions were determined in the electron ener gy range 0-100 eV. The obtained results are compared with data on excitatio n cross sections of PbII in electron-atom collisions.
