摘要：

We have carried out quantal calculations for the dielectronic recombination of C3+ in an electric field. We have used these results in a collisional-radiative model for a carbon seeded hydrogen plasma. We find that the plasma microfield increases the effective dielectronic recombination rate coefficient for C3+ by only 40% at n(H) = 10(9) cm-3, for example, compared to the near factor of 3 enhancement predicted by Reisenfeld et al. in 1992. The large effects predicted by Reisenfeld et al. over a wide range of densities are the result of an over-estimation of the electric field enhancement of dielectronic recombination by their approximate calculations.
