The electron heating rate and ion chemistry in the thermosphere above Wallops Island during the solar eclipse of 7 March 1970
(Elsevier, 1972-04)
An identical pair of thermosphere probes measured the N2 concentration and temperature, the ion composition and concentrations and the electron temperature up to 290 km about 30 min and 5 min before totality during the 7 ...
Quantum Mechanical Calculation of Molecular Radii. I. Hydrides of Elements of Periodic Groups IV through VII
(The American Institute of Physics, 1972-05-01)
The fraction of the total electron density within a sphere having the empirical van der Waals radius is calculated for the atoms of eight elements, using Hartree‐Fock atomic wavefunctions. The sphere is found to contain ...
Localized In‐Band Rotational Phonons in Mixed Molecular Crystals: Electronic Spectra of Naphthalene Doped Biphenyl and Durene
(The American Institute of Physics, 1972-04-01)
Coulomb energies of spherical nuclei
(Elsevier, 1972-02-14)
A phenomenological Coulomb energy equation has been derived for spherical nuclei with diffuse surfaces. Contributions from the direct and exchange Coulomb energy and from the electromagnetic spin-orbit interaction are ...
Electrohydrodynamic Solutions for Nematic Liquid Crystals
(The American Institute of Physics, 1972-06-01)
We have solved the boundary value problem associated with the Williams domain mode and the variable grating mode in nematic liquid crystals. Using linearized electrohydrodynamic equations of motion, standard constitutive ...
Theory of the piezomagnetic effect in titanomagnetite-bearing rocks
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1972-12)
The stress sensitivities S x and S R of susceptibility and remanence for titanomagnetite-bearing rocks are calculated in terms of magnetostriction constants λ 100 and λ 111 and anisotropy constants K 1 , K 2 of the magnetic ...
Peripherality and [pi]N scattering
(Elsevier, 1972-03-06)
[pi]N amplitudes, as far as they have been deduced, are used with an absorbed Reggeon exchange model to obtain amplitudes at larger -t with specified phases. Thus, satisfactory peripheral amplitudes are found. The phase ...
Random‐Coil Dimensions and Dipole Moments of Vinyl Chloride Chains
(The American Institute of Physics, 1972-01-01)
A rotational isomeric state model with neighbor interactions is used to calculate mean‐square unperturbed dimensions and dipole moments for vinyl chloride chains CH3�(CHCl�CH2�)xHCH3�(CHCl�CH2�)xH having degrees of ...
Equal-path time-of-flight neutron diffraction
(Elsevier, 1972-03-15)
Measurements of the neutron diffraction patterns of liquids and non-crystalline solids with crystal spectrometer facilities and time-of-flight diffraction techniques are discussed. It is shown that measurements with an ...
A Pomeron model which needs no decoupling
(Elsevier, 1972-12-25)
We present a model in which the Pomeron is a related pair of factorizable Regge poles both with intercept one. Our model requires a cut (fixed or moving) with a branch point intercept one. In this model the triple Pomeron ...
