Electron-capture collisions at keV energies of boron and other multiply charged ions with atoms and molecules. II. Atomic hydrogen

Single electron-capture cross sections have been measured for boron ions Bq+ with initial charges q=2, 3, and 4 incident on an atomic hydrogen target. The cross sections σ₂₁ and σ₄₃ are large and show little dependence on the ion energy for the range studied, $6q$ to $23q$ keV. The cross section σ₃₂ increases with increasing energy in this same range. Also reported is a survey of single electron-capture cross sections for ions of carbon (2≤q≤4), nitrogen (2≤q≤5), and oxygen (2≤q≤5) at the single energies $8q$ keV also incident on atomic hydrogen.
