Abstract: Application of the methods and concepts of magnetism to provenance determination of archaeological artifacts
(The American Institute of Physics, 1979-11-01)
The magnetic properties of material artifacts depend on their bulk compositions, the phase assemblages, the crystal‐ and micro‐structures of the phases and their thermal histories. The magnetic properties of an object ...
Spectroscopic and optically detected magnetic resonance studies of PO2-in potassium chloride. I. Electronic and vibrational states
(Elsevier, 1979-06-01)
The phosphorescence and phosphorescence excitation spectra of phosphorus activated single crystals of potassium chloride have been examined at 4.2 K. The "color center" responsible for the blue emission in these samples ...
Intensity dependence of transmission of electromagnetic radiation through an overdense Z‐pinch plasma
(The American Institute of Physics, 1979-03-15)
The interaction of a 10.6‐μm‐wavelength electromagnetic wave with an independently created overdense plasma has been investigated at incident intensities on either side of the field‐strength condition Vosc/Vth=1. An intensity ...
Application of ART to time-coded emission tomography
(IOP Publishing Ltd, 1979-09-01)
Using the Algebraic Reconstruction Techniques (ART) a method is introduced for division of the correlation coefficients into subsets allowing the three-dimensional reconstruction to be accomplished on a minicomputer. Results ...
Streaming birefringence in extensional flow of polymer solutions
(Steinkopff-Verlag; Dr. Dietrich Steinkopff Verlag ; Springer Science+Business Media, 1979-07)
The stress and birefringence in liquid filaments undergoing an extensional flow were measured in an isothermal filament-spinning apparatus. In conjunction with these measurements, an experimental arrangement is described ...
Dynamic polarization in radiation resistant materials
(Elsevier, 1979-02-15)
Measurements of spin effects in small cross section processes have shown the need for more radiation resistant polarized target materials. We have examined the dynamic polarization of a number of substances which are known ...
Size effects in small electron-hole drops
(Elsevier, 1979-06)
The self-consistent formulation of density functional theory is used to calculate the single-particle properties of electron-hole droplets in Ge with between 10 and 120 pairs. Results are presented for the recombination ...
Corrections to the StermanWeinberg jet formula
(Elsevier, 1979-02-26)
The fraction of hadronic final states from e+e- annihilation consisting of two jets is calculated exactly to lowest order in QCD perturbation theory. This improves the Sterman-Weinberg expression increasing its range of ...
Period of homogeneous oscillations in the ferroin‐catalyzed Zhabotinskii system
(The American Institute of Physics, 1979-12-01)
This work is primarily an experimental investigation of the ferroin‐catalyzed Zhabotinskii system [malonic acid (MA), sulfuric acid, sodium bromate, traces of bromide ions, and ferroin]. We measure the transmittance as a ...
Solid state- and magneto-chemistry of the SrO-Fe2O3 system : III. The non-existence of single-phase "SrFe2O4"
(Elsevier, 1979-11)
A detailed Mossbauer investigation of 1 : 1 SrO : Fe2O3 has shown that a single phase with the SrFe2O4 composition does not exist in the SrO-Fe2O3 system when SrCo3 and Fe2O3 are reacted in air. A multiphase assemblage of ...
