Chemi-ionization in K-I collisions. I. Integral cross sections

Abstract

Accurate partial and integral cross sections for chemi-ionization have been calculated for a two-state model representing collisions between ground state K and I atoms from threshold to 6 eV relative energy using a coupled equations method. In addition, these quantities have been calculated in the Landau-Zener and Stueckelberg approximations. They furnish results for the charge transfer channel which agree with the accurate ones, down to the threshold energy, to within 7%. The integral cross sections for charge neutralization are obtained from the ionization cross sections by microscopic reversibility, and it diverges as E⁻¹.
