“…All of the measurements presented in this paper were made in an ultrahigh vacuum chamber that was maintained at 10 Torr. The details of this multipurpose chamber have been described elsewhere [20].…”

“…For K-shell ionization of an atom, the direct ionization (DI) of a target electron to the continuum has been shown to be a principal mode of interaction for th«egion Z, «Z2 and vi &&v2K (Ref' [15]), where Zi and Z~r efer to the incident and target atomic numbers, and u, and u2z refer to the incident-ion and target E-shell electron velocities, respectively. The DI process has been described in the first-order Born approach by the plane-wave Born approximation [15] [20]. Thin targets (see Table I) were prepared by vacuum evaporation and deposition of the elements of interest onto 5-pg/cm carbon foils, except for magnesium, which was evaporated onto gold backings.…”
