The dependence of the convoy electron yield on target thickness is found at a transmission of 50 MeV 3He2+ ions through thin carbon foils (1<ρ{variant}ξ<100 μ/cm2), where the charge state equilibrium of the transmitted ions is not attained. It was found that the convoy electron yield is proportional to the fraction of He+ in the transmitted ions. The probabilities of convoy electron production (per unit length), and thus the cross sections of ELC (electron loss to continuum) and of ECC (electron capture to continuum) and the mean free path for convoy electrons were estimated with the two-step model in which the convoy electrons are produced in the bulk and are transported out of the solid.
