Conductivity of a system of metallic particles dispersed in an insulating medium
(The American Institute of Physics, 1973-06)
The variation of the conductivity of metal‐particle—insulator systems with the volume percent of metal is explained in terms of an ``effective medium'' theory.
Splitting of the phonon spectrum in 3 He- 4 He solutions
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-07)
The dynamic structure function for 4 He- 4 He density correlations S 44 ( k , ω) is calculated as a function of the wave vector k and frequency ω for a simple model of a 3 He- 4 He solution at various temperatures and small ...
Thermal conductivity of neon, argon, and xenon at high temperatures
(The American Institute of Physics, 1973-09-01)
Thermal conductivities λ of neon, argon, and xenon were measured at 760 mm Hg in the ranges 1000–1500 °K (neon, xenon) and 1000–2500 °K (argon). The data were correlated by expressions of the form λ = a Tb, where a and b ...
A class of loss functions of catenary form
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1973-03)
The catenary form of loss function is considered in the framework of Bayesian decision theory. The mathematical tractability of this form seems to be unrecognized; it contains quadratic loss as a limiting case. For various ...
Redundancy modulation for coherent imaging systems
(Elsevier, 1973-01)
In order to image continuous-tone transparencies with coherent light, special types of diffuse speckle-free illumination are required to achieve high image quality. Several types of speckle-free modulation have been ...
Computation of electric dipole matrix elements for hydrogen fluoride
(Elsevier, 1973-02)
The electric dipole matrix elements of hydrogen fluoride have been calculated by numerical integration for transitions involving large quantum numbers [upsi], J. Overtones have been included through [Delta][upsi] = 5 . ...
Wigner and Racah coefficients for SU3
(The American Institute of Physics, 1973-12)
A general yet simple and hence practical algorithm for calculating SU3⊃SU2×U1SU3⊃SU2×U1 Wigner coefficients is formulated. The resolution of the outer multiplicity follows the prescription given by Biedenharn and Louck. ...
The reaction 26Mg(d, [tau])25Na and the structure of 25Na
(Elsevier, 1973-04-16)
The nuclear structure of the nucleus 25Na has been studied with the (d, [tau]) proton pick-up reaction on 26Mg at a bombarding energy of 29 MeV with an energy resolution of 25 to 30 keV FWHM. Excited states in 25Na have ...
Effect of excluded volume on the dipole moments of chain molecules
(The American Institute of Physics, 1973-10-01)
Dielectric constants have been determined for dimethylsiloxane chains (CH3)3Si[OSi(CH3)2]x OSi(CH3)3 in the thermodynamically good solvent cyclohexane and in the undiluted state, for degrees of polymerization x + 1 ranging ...
Light scattering from an exploded lithium wire plasma
(The American Institute of Physics, 1973-06)
A thin lithium wire was extruded and exploded in vacuum and the resulting plasma was studied during the first 2 μsec of the discharge. Included in the study were scattering of a Q‐switched ruby laser beam, high‐speed streak ...
