Magnetohydrodynamics at Small Magnetic Reynolds Numbers
(The American Institute of Physics, 1962-04)
Two problems are considered, each of which represents a class of flows. In the first problem the motion is induced by passage of electric current through an incompressible viscous electrically conducting fluid contained ...
The rotation spectrum of methyl alcohol from 20 cm-1 to 80 cm-1
(Elsevier, 1963)
The rotational spectrum of methanol vapor has been measured from 20 cm-1 to 80 cm-1. The observations have been compared with the predictions of Burkhard and Dennison and for the most part good agreement is found. Some ...
Singular Integral Equations
(The American Institute of Physics, 1966-12)
The integral equationP∫cK(ζ′,ζ)ζ′−ζφ(ζ′)dζ′=h(ζ)φ(ζ)+f(ζ)is shown to have simple solutions obtained by standard and elementary methods if h and K have appropriate analytic properties.
An image intensifier-scintillator device for determination of profiles and images of weak beams of ionizing particles or X-rays
(Elsevier, 1961)
An instrument for determining the shape and intensity distribution of particle and X-ray beams has been developed using an image intensifier tube together with a bundle of filaments of scintillator. A description of the ...
Kinematical constraints of helicity amplitudes
(Elsevier, 1969-07-15)
The kinematical constraints of helicity amplitudes are studied using the general ideas of Jackson and Hite. The helicity amplitudes are expressed in terms of a Taylor series expansion from which all constraints at threshold ...
Energy‐Moment Methods in Quantum Mechanics
(The American Institute of Physics, 1967-10-15)
Three quantum‐mechanical computational techniques based on energy moments, μk = ∫ dqψ*(q)Hkψ(q)μk=∫dqψ*(q)Hkψ(q), and semimoments, νk(q′) = [Hkψ(q)]q = q′νk(q′)=[Hkψ(q)]q=q′, are formulated. The μ method, which employs the ...
Infrared Study of Lamellar Linking by Cilia in Polyethylene Single‐Crystal Mats
(The American Institute of Physics, 1969-10)
The infrared spectra of single‐crystal mats of physical mixtures of polyethylene and perdeuteropolyethylene show splittings of CH2 and CD2 bending and rocking modes which are smaller than those for the pure species. This ...
Infrared target and background radiometric measurements--concepts units and techniques
(Elsevier, 1963-09)
This report discusses concepts units and techniques for making and describing measurements of radiation from targets and backgrounds.
