Title: Electron capture by slow multicharged ions in atomic and molecular hydrogen

Abstract

Measured cross sections for electron capture by a variety of multiply charged ions in collisions with atomic and molecular hydrogen are presented. The data are primarily for He-like and Li-like ions of B, C, N, and O in the velocity range 0.4--1.0 x 10/sup 8/ cm/sec. The electron-capture cross sections for these ions are typically 3 x 10/sup -15/ cm/sup 2/ in the velocity range tested. Comparison is made between these data and a number of recent theoretical predictions. While no simple scaling rules apply to these low-velocity data, for initial charge q > or = + 4 the cross sections are essentially characterized by initial ionic charge rather than by projectile mass or electronic structure.
