Quantum mechanically accurate calculations are carried out for the Mu+ Hz and Mu + Dz reactions using the hyperspherical coordinate approach. The results for the rate constant are in good agreement with experiment. Comparisons are also made with other more approximate calculations. The effect of ini

β¦ Synopsis
The bimolecular rare conslanls for the thermal chemical reaclions 01 muonium (Mu): Mu + H2 + MuH + H and Mu+ D2 + MuD+D. have been measured in the temperalure range 610-650 K. For the hydrogen reaction. log A (err? molecule-' s-l)= -9.6&0.4md fC,-13.8+1.5 kcol mole-'. while for the druvxium rexCon log A (cm3 molecule-' s-') = -9.12 1.2 and Ea = 17.22 4.1 kcal mole-'. These results compare well with variational wmsition slate theory calcularions carried OUL on the Liu-Siegbnhn-Truhlar-Horowitz potemial surface.

The MSR imuonium spin rotation) technique was used to measure the chemical reaction rate for Mu + F2 -+ MuF+ F in N2 moderator at =l atm from 295 to 383 K giving the Arrhenius expression: log10 k (Q/mole s) = (10.83 f 0.20) -(200 + 50)/T. with k = (I.46 k 0.11) X 1O'O E/mole sat 300 K.

A quasiclassical smooth sampling calculation ofreaction probabilities has been carried out for the collinear reaction X + F2 (u = 0) -~XF + F (X = Mu, H, D, T) in the threshold region. The quasiclassical reaction probabilities are in poor agreement with corresponding quantum results. We attribute th
We have extended the highly precise laser photolysis/cw laser-induced fluorescence technique to the study of CN-radical reaction kinetics. We investigated the reaction of CN with O2 over the temperature range 295-7 IO K. The measured reaction-rate coeflicients are well represented over this temperat
