摘要：

This paper reports on the measurement of the absolute cross sections of the following associative ionization processes: H-2(+) + H- --> H-3(+) + e H-2(+) + D- --> H2D+ + e D-2(+) + H- + D2H+ + e D-2(+) + D- --> D-3(+) + e. Measurements were carried out using merged beams and chopping the negative beam to evaluate the background. The measurements cover the barycentric energy range from 0.07 to 10 eV. The four cross sections were, within experimental error, equal both in magnitude and energy dependence.
