Abstract

Through determinations of the widths of ion cyclotron resonance lines as a function of pressure and electric field strengths, the ion-molecule collision cross sections of H⁺, H₂⁺, H₃ ⁺, He⁺, Ar⁺, N₂⁺, N ⁺, O₂⁺, O₂^-, and O ^- were obtained. Agreement with dc mobility data was found. In particular, the minimum in collision frequency for H₃⁺ in H₂ at E/P₀=60 V/cm·torr was confirmed. The cross sections for H₂⁺ in H₂ are 275 and 68 Å² at low and high E/P, respectively.
