Muonium (Mu) is considered the lightest isotope of the H atom. We report the rate constant for the Mu + H2(vibrational quantum number n = 1) ? MuH + H reaction determined by measurements at 300 K and converged quantum mechanical calculations. The measurements are a sensitive probe of the high-curvature region in the entrance valley of the potential energy surface (PES), and thus provide a qualitatively different probe of the PES than that provided by any previous experiment. Comparisons are made with earlier results for D + H2(n = 1) and with the corresponding thermal reaction rates.
