The electronic structure of ilvaite and the pressure and temperature dependence of its 57Fe Mossbauer spectrum
(Elsevier, 1980)
57Fe Mossbauer measurements have been performed on four, chemically analyzed samples of the mixed-valence mineral ilvaite, Fe3+Fe22+(Si2O7)O(OH), as polycrystals and oriented-single-crystals between 300 and 475 K and between ...
Reply to Comment on ‘‘Experimental test of the Anderson–Mott transition model for excitation transport’’
(The American Institute of Physics, 1980-07-15)
It is argued that the critical electronic energy transfer EET concentrations observed in naphthalene2,4 are not accounted for by the Klafler and Fortner1,3,5 models of an Anderson transition. (AIP)
A study of inclusive [Lambda] polarization from hydrogen and other targets at 28 GeV
(Elsevier, 1980-02-25)
We report measurements of inclusive [Lambda] polarization, produced by unpolarized protons incident at several momenta (20, 24, and 28.5 GeV/c) onto hydrogen, deuterium, and beryllium targets. A large polarization from ...
A physical picture for the phase transitions in ZN symmetric models
(Elsevier, 1980-08-11)
We show how the phase transitions in ZN symmetric spin and gauge theories can be understood as being caused by condensations of topological excitations. For the two-dimensional ZN periodic gaussian and vector Potts models, ...
e + e − annihilation at high energies and search for the t -quark continuum contribution
(Springer-Verlag, 1980-06)
Measurements of R , sphericity and thrust are presented for c.m. energies between 12 and 31.6 GeV. A possible contribution of a t continuum can be ruled out for c.m. energies between 16 and 31 GeV.
Application of fast Fourier transforms to EPR spectra of free radicals in solution
(Elsevier, 1980-08)
A method of reducing EPR spectra of free radicals in solution is presented in detail. This method is based on the use of the fast Fourier transform algorithm and curve fitting in the Fourier space by weighted least-squares ...
A new proof of absence of positive discrete spectrum of the Schrödinger operator
(The American Institute of Physics, 1980-09)
A new method to prove the absence of positive discrete spectrum of the Schrödinger operator is given.
Tunable laser study of the [nu]10 + [nu]11 band of cyclopropane
(Elsevier, 1980-06)
Diode laser measurements of the [nu]10 + [nu]11 (ltot = +/-2) perpendicular band of cyclopropane have led to the assignments of roughly 600 lines in the 1880-1920-cm-1 region. Most of the spectra were recorded and stored ...
Pseudopotential SCF–MO studies of hypervalent compounds. II. XeF+5 and XeF6
(The American Institute of Physics, 1980-07-01)
New evidence bearing upon the anomalous properties of xenon hexafluoride has been obtained via the ab initio molecular orbital approach applied successfully to the di‐ and tetrafluorides in paper I. Structures of both XeF+5 ...
Bispectral analysis as a probe of quasielastic light scattering intensity fluctuations
(The American Institute of Physics, 1980-06-01)
The bispectrum 〈I(0)I(t)I(τ)〉 of the intensity I of light scattered quasielastically from a fluid system is shown to be a potentially useful tool for studying complex fluids. Bispectra and time cumulants are calculated, ...
