Electron-ion recombination in a weakly ionized molecular gas has been studied by the application of molecular-dynamics and Monte Carlo simulations. Plasma screening effects have been investigated for electron densities exceeding 10/sup 13/ cm/sup -3/. Screening can reduce the recombination rate coefficient ..cap alpha.. by as much as one half, for n/sub e/ = 10/sup 15/ cm/sup -3/, before ..cap alpha.. increases again with n/sub e/ due to electron-stabilized three-body collisional radiative recombination. In a plasma with an applied electric field, ..cap alpha.. is found to decrease approximately proportional to (E/N)/sup -1/ for E/N greater than a threshold value.
