We have calculated the effective rate coefficient for molecular assisted recombination (MAR) by using our collisional‐radiative model for atomic and molecular hydrogen with recent atomic and molecular data incorporated. The result for the vibrational ground state molecule agrees very well with the original rate coefficient proposed by Krashennikov et al. The rate coefficient depends strongly on the initial vibrational excitation of the molecule released from the wall.
