Electron energy distribution functions (edf) and related parameters have been calculated in the post-discharge regime of vibrationally excited He--CO mixtures by solving the Boltzmann equation including superelastic vibrational collisions. The calculations point out to the importance of small concentration of CO molecules in affecting both edf 's and related quantities in the post-discharge reigme. In particular, the mixture closely follows the behavior of pure CO for molar fractions of CO (X/sub CO/) approximately equal to 20%. Helium affects edf 's by increasing elastic losses in the post discharge, for X/sub CO/<20%, leading to average electron temperatures, T/sub e/, lower than the corresponding vibrational temperatures, theta/sub 1/. The results obtained by using Treanor's and Boltzmann distributions emphasize the role of excited vibrational levels (v>2) in affecting edf and the average electron energy.
