摘要: The basic equation of the rate constant a two‐body reaction, κ= ∫ vg vi fgas(vg)fion(vi)vrσ(vr)dvidvg, is used to infer cross section from ion—molecule reactions measured in drift tubes as function E/p0, κ, vr, and σ are constant, relative speed, section, respectively. Maxwellian distribution at gas temperature for fgas. A displaced Maxwellian, having parameter defined by diffusion coefficients, displacement 〈 vz〉=vd, fion. vd velocity.
