Abstract

Absolute cross-sections have been measured and compared to CTMC-calculations for single and double-electron removal from H− in collisions with Ar^q+ ions (q ≤ 8) at E_c.m. = 50 keV. The single-electron removal cross-sections are found to scale with q^1.3, and for the H⁻ + Ar⁴⁺ system, this cross-section is found to have a weak energy dependence from 3 keV to 100 keV. A major implication of our measurements is that plasma neutralizers based on multiply charged ions for high-efficiency conversion of intense H⁻ beams into H⁰ gain little in expected reduced length due to the inapplicability of q²-scaling in the H⁻ single-electron removal cross-section. © 1989, IOP Publishing Ltd.
