Formation of metastable helium atoms by electron capture during the passage of fast He+ions through gases
Year: 1971
Type: article
Abstract: A beam attenuation technique, developed previously in this laboratory, has been used to investigate the formation of metastable helium atoms by electron capture of 10-200 keV He + ions in hydrogen, helium, neon, argon, krypton and nitrogen. The fractions of metastable atoms formed in both thin and thick targets have been determined and used to obtain separate cross sections for the formation of ground state and metastable atoms. The equilibration of the metastable component of the beam in thick targets has also been described quantitatively in terms of the relevant charge changing collisions.
