Description

Beams of electrons are shown to be able to control the motions of neutral molecules. A beam of electrons coaxial with a neutral beam of KCl molecules can restrict the divergence of the KCl beam to increase its signal on a detector by up to a factor of 10$sup 4$. Further, an electron beam can pump molecules from the residual gas in a vacuum chamber by forcing them to move preferentially along the electron beam into another chamber where they are detected by a mass spectrometer. Inelastic scattering of CsI by Ar and Xe and of CsCl by Ar with ... continued below

Description

Beams of electrons are shown to be able to control the motions of neutral molecules. A beam of electrons coaxial with a neutral beam of KCl molecules can restrict the divergence of the KCl beam to increase its signal on a detector by up to a factor of 10$sup 4$. Further, an electron beam can pump molecules from the residual gas in a vacuum chamber by forcing them to move preferentially along the electron beam into another chamber where they are detected by a mass spectrometer. Inelastic scattering of CsI by Ar and Xe and of CsCl by Ar with velocity selection and analysis at thermal energies shows large cross sections for the transfer of energy in amounts up to several vibrational quanta for both excitation and deexcitation of the molecules. The reaction LiCl + H $Yields$ Li + HCl is studied as it occurs on a Re surface as are the yields of positive and negative ions formed from cesium halides incident on a Nb surface. (auth)
