Instability of a Liquid Film Flowing down an Inclined Plane
(The American Institute of Physics, 1967-02)
The mechanism of the instability of a layer of liquid flowing down an inclined plane is studied. First, the instability of the flow with respect to Tollimen‐Schlichting wave is investigated. The results obtained are then ...
Expansion Theorem for the Linearized Fokker‐Planck Equation
(The American Institute of Physics, 1967-04)
The linearized Fokker‐Planck kinetic equation for each component of a homogeneous, nondegenerate, fully ionized plasma is separated by means of a spherical harmonic expansion into an infinite set of singular intergo‐differential ...
Results on the Analyticity of Many‐Body Scattering Amplitudes in Perturbation Theory
(The American Institute of Physics, 1967-12)
The problem of analytic continuation of the many‐body scattering amplitude associated with a perturbation‐theory diagram under the rotation of the final momenta from real to complex momenta, k → (1 + iθ)k, is studied. It ...
Neutron—Diffraction Study of Cr and Cr Alloys
(The American Institute of Physics, 1967-03-01)
The principle quantities which parameterize the antiferromagnetism of Cr are studied by neutron diffraction as a function of temperature, pressure, magnetic field, and concentration of solute atoms. In order to account for ...
Reflection of Electrons by Standing Light Waves: A Simple Theoretical Treatment
(The American Institute of Physics, 1967-03-15)
The reflection of electrons by standing light waves, i.e., the stimulated Compton scattering proposed by Kapitza and Dirac, has been treated by applying the Born approximation. The probability that an electron will be ...
Influence of Nonbonded Interactions on Molecular Geometry and Energy: Calculations for Hydrocarbons Based on Urey—Bradley Field
(The American Institute of Physics, 1967-11-15)
A modified Urey—Bradley potential energy function comprised of quadratic terms for bond stretches, bond‐angle bends, and torsional displacements together with analytical expressions for pairwise nonbonded interactions was ...
Production of Monodisperse Sprays
(The American Institute of Physics, 1967-04)
A technique for producing monodisperse sprays is described. The technique makes use of Rayleigh's criterion for the breakup of capillary jets by mechanically vibrating a number of uniform size capillary needles arranged ...
Wigner Method in Quantum Statistical Mechanics
(The American Institute of Physics, 1967-05)
The Wigner method of transforming quantum‐mechanical operators into their phase‐space analogs is reviewed with applications to scattering theory, as well as to descriptions of the equilibrium and dynamical states of ...
Structure of Turbulence in the Boundary Layer near the Wall
(The American Institute of Physics, 1967-09)
Previous measurements of space‐time correlations of turbulent wall pressure and velocity in the boundary layer were extended to include space‐time correlations between the wall pressure and all three velocity components ...
