Correction factors to measured values of the ion–ion recombination coefficient, which are required because of nonuniform ion density and diffusion losses, are calculated from computer solutions to the differential equation for simultaneous recombination and diffusion. Results for plane-parallel ion chambers are given as a function of ion age for an initially uniform ion distribution over a considerable range of ion density and electrode spacing, and for a collimated distribution for two particular combinations of ion density and electrode spacing. Corrections to be applied to some reported experimental ion–ion recombination coefficients are estimated.
