Neutron-nuclei total cross sections at 27 GeV/c
(Elsevier, 1968-08-05)
The total cross sections for 27 GeV/c neutrons on eight heavy elements, Be through U, has been measured and found to obey the empirical relationship [sigma]T = 48A0.75mb.
Recoupling Coefficients for the Group SU(3)
(The American Institute of Physics, 1967-01)
The Hilbert space method, employed in the previous article to obtain the coupling coefficients of SU(3), is used here to obtain the recoupling, or 6(λμ), coefficients of SU(3). The coefficients are formulated in terms of ...
Construction of a Shock Tube for Metallic Vapors
(The American Institute of Physics, 1969-05)
The construction and operation of a heated shock tube (often called mercury shock tube due to its immediate application) are described in some detail. Experimental observations of strong shocks in mercury gas are presented ...
Stability of a Horizontal Fluid Interface in a Periodic Vertical Electric Field
(The American Institute of Physics, 1968-07)
The stability of the interface in the presence of a periodic electric field is considered. It is shown that the stability is governed by a Mathieu equation, that the interface can be unstable even if the electric field is ...
VO2+ and X‐Ray Produced V2+ in Tutton Salt
(The American Institute of Physics, 1964-04-15)
The electron spin resonance spectrum of the vanadyl ion (VO2+) in single crystals of Zn (NH4)2(SO4)2⋅6H2O is studied and the properties of x‐ray produced V2+ are compared to those of the V2+ grown directly into the same ...
Determination of the Phonon Spectrum of Polyethylene by Neutron Scattering
(The American Institute of Physics, 1965-08-01)
LENSLESS FOURIER‐TRANSFORM METHOD FOR OPTICAL HOLOGRAPHY
(The American Institute of Physics, 1965-05-15)
Axial Quasi‐Brillouin Streams
(The American Institute of Physics, 1962-07)
A nonlaminar model for axially uniform electron streams is postulated and conditions for which the model is consistent with physical requirements are derived. The character of the current density profiles permitted by the ...
Energy‐Distribution Function for Hot Atoms Produced by Nuclear Transformations
(The American Institute of Physics, 1964-09-15)
The energy‐distribution function for hot atoms produced by nuclear transformations is examined in terms of the fraction of the initial hot‐atom energy. Energy dependent and independent asymmetric scattering is specifically ...
Wave Excitation in Compressible Plasma and Equivalence Relations
(The American Institute of Physics, 1967-11)
A general, unified solution of the wave excitation due to electric‐current sources, magnetic‐current sources, fluid‐flux sources, and mechanical‐body sources in a compressible plasma which may be anisotropic and inhomogeneous ...
