Rate of aerodynamic atomization of droplets
Journal of Spacecraft and Rockets, 1965A TOMIZATION of large liquid droplets subjected to high ^J^relative gas velocities is of interest to the field of liquid propellant combustion and instability processes, which occur in rocket engines. It is desirable to have quantitative information for the time rate of mass loss from the droplet as a function of the gas stream and droplet ...

Rate of Recombination of Nitrogen Atoms
The Journal of Chemical Physics, 1958The rate of recombination of nitrogen atoms by three-body collision has been determined at room temperature and 0.5–1.3 mm pressure. The nitrogen was dissociated (about 3–6% nitrogen atoms) in a condensed discharge and pumped continuously through a glass tube 4.2 cm i.d. and 2.5 m long.

Effects of nonequilibrium plasmas on atomic reaction rates
Physical Review E, 1994The influence of electron-density fluctuations on atomic reaction rates is studied in a hydrogen model plasma. We show that the effective ionization rates are found to be extremely sensitive to deviations of the electron density from the local thermal equilibrium (LTE) distribution, while the effective recombination rates are relatively stable against ...

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.

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.

Rate of recombination of nitrogen atoms
The Journal of Chemical Physics, 1979Decays of the concentration of N(4S) atoms in the Lewis–Rayleigh nitrogen afterglow were measured in a static mode, with a mass spectrometer that was calibrated against NO titration. The rate constant for recombination of N(4S) atoms with N2 molecules as the third body [N(4S)+N(4S)+N2→N2+N2] was determined as 7.2×10−33 cm6 molecule−2 sec−1.

Surface diffusion, atomic jump rates and thermodynamics
Surface Science, 1981Abstract The connection is established between the surface diffusivity D (θ) and Γ(θ), the rate of atom jumps in an adsorbed gas at a coverage θ. For a Langmuir layer, the two quantities are related at all coverages by D (θ) = Γ(0) λ 2 , where λ. is the jump distance, For interacting adatoms, however, the diffusivity also depends upon the chemical ...

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.

Atomic emission rates in photonic band structures
Optical Society of America Annual Meeting, 1992There has been a great deal of interest lately in periodic dielectric materials that exhibit photonic band structures. One of the more interesting features of such a substance is its ability to alter the emission rate of probe atoms embedded in the periodic lattice. Large enhancements and complete inhibition of emission rates can be obtained.
