Description
The temperature dependence of the gas phase spin exchange reaction rates for muonium collisions with O2 and NO has been measured over the temperature range 295 to 478 K. In both cases the bimolecular rate constant k(T) was found to vary essentially as T/sup 1/2/, leading to the following temperature independent spin exchange cross sections: sigma/sub SE/(Mu+NO) = (10.5 +- 0.6) x 10-16 cm2 and sigma/sub SE/(Mu+O2) = (9.1 +- 0.7) x 10-16 cm2. These results are in quantitative agreement with the H+O2 and H+NO results reported by Gordon et al., demonstrating that there is no isotope effect in spin exchange in this temperature range
