Description
Thermal reaction rates for the gas-phase reaction Mu + C2H6 → MuH + C2H5 have been measured by μSR over the temperature range 510-730 K. The usual Arrhenius expression, k = A exp(-Ea/RT), fits the data well, giving parameters A = 1.0 x 10-9 cm3 molecule-1 s-1 and Ea = 15.35 kcal/mol. The activation energy Ea is 5.5 kcal/mol higher than for the H atom variant of this reaction, indicating a marked difference in reaction dynamics. Preliminary analysis indicates a still greater difference between Mu and H for the corresponding CH4 reaction. (orig.)
