The rate of homogeneous recombination of fluorine atoms
Chemical Physics Letters, 1974Abstract The recombination rate of fluorine atoms has been determined in a Teflon-coated flow reactor at 295°K and pressures of 10–81 torr with Ar as the carrier gas. Concentrations of atomic fluorine are measured by titrating with Cl 2 and using the intensity of chlorine atom recombination emission as an endpoint indicator.

A self-developed double-nozzle gas atomization technique was used to produce AlSi10Mg powder. Effects of delivery tube diameter, gas pressure, and melt superheat on powder characteristics were investigated.

On the rate of the reaction of ammonia with oxygen atoms
Chemical Physics Letters, 1984Abstract Absolute rate constants for the reaction of O( 3 P) with ammonia were measured over the temperature range 448–841 K by means of a laser photolysis-chemiluminescence technique. The data were fitted with the following Arrhenius expression: k = 3.42 × 10 −11 exp[-(9000 ± 600 cal/mole)/ RT ] cm 3 molecule −1 s −1 .

The Absolute Rate of Homogeneous Atomic Reactions
The Journal of Chemical Physics, 1935The absolute rate of the recombination of three hydrogen atoms is calculated entirely theoretically. The manner in which rotation determines the dimensions of the activated complex in cases having little or no activation energy is discussed. The theoretical data are in good agreement with the experimental rates of Steiner and of Amdur.

Homogeneous rate of recombination of hydrogen atoms
Canadian Journal of Chemistry, 1968The rate of decay of hydrogen atoms has been measured in a conventional type of discharge-flow system at temperatures between 190–350 °K. The recombination fitted the equation[Formula: see text]where ks is the first order surface rate constant. No three-body recombination for M = H was observed at the low levels of dissociation (2–5%) employed.

Il Nuovo Cimento, 1961
A study has been made of theK Auger transitions in the light elements of nuclear emulsions. Of 382 stopping μ−-mesons, 1016 were observed to decay. 5 of these had associated short-range electrons whose energies were consistent with theK transitions of CNO.

Temperature Dependence of Atomic Decay Rate
Chinese Physics Letters, 2012We investigate the decay rate of an atom in a two-dimensional optical microcavity in which there exists a Bose-Einstein condensation of photons. It is found that below the critical temperature Tc, the atomic decay rate depends on the absolute temperature T. Especially, at absolute zero temperature almost all photons are in the condensate state, and the

Absolute Rates of Four-Atom Reactions
The Journal of Chemical Physics, 1936Equipotential surfaces such as one encounters in valence problems and particularly in the calculation of absolute rates, are discussed in a ``bond space'' instead of configuration space, with much simplification resulting both in the general aspects and in the practical handling of such problems.
