Single and double ionization of He by 0.5 - 8 MeV/q Li{sup 1+} (q=1.2.3) ions
- Western Michigan Univ., Kalamazoo, MI (United States)
Single and double ionization of a He target by Li{sup q+} projectiles (q=1,2,3) have been investigated in the energy range 0.5 - 8 MeV/q at Western MIchigan University. Target ionization associated with specific outgoing projectile charge states was identified using time-of-flight techniques. The primary goal of this work was to investigate the ionization of He by {open_quotes}structured{close_quotes} projectiles and to determine the effect of the projectile electrons on the ionization process. For all energies investigated, the double-to-single ionization ratios associated with electron capture and loss are significantly larger than those for direct ionization (no projectile charge change). The direct double-to-single ionization ratio for Li{sup 3+} is in good agreement with the scaling prediction of Knudsen et al. The present results are compared with the He+ + He measurements of Forest et al.
