Experimental studies of electron impact depopulation of excited states of atoms: applications to laser development for fusion and isotope separation. Final report, 1 January 1977-30 June 1979

OSTI ID:5279034
Motivated by the need for measurements of metastable depopulation mechanisms of Ar and Kr in the KrF rare-gas monohalide excimer laser, an ultra-high vacuum triple crossed-beams apparatus has been designed, fabricated, and assembled for the purpose of studying electron scattering from excited states of Ar and Kr atoms. A beam of metastable rare gas atoms, produced by near-resonant charge transfer of rare gas ions with alkali neutral atoms, is crossed by an electron beam and a far-red laser beam along mutually orthogonal axes. A hemispherical electron monochromator-spectrometer pair is used to measure the cross section for electron scattering from the 2p/sub 9/ excited state of the rare gas atom. Testing of parts of the assembled apparatus has been completed.
