Relationships among Generalized Phase‐Space Distributions
(The American Institute of Physics, 1969-02)
The generalized phase‐space distributions, including the Wigner distribution, are presented in terms of expected values of generating operators. A generalization of the Weyl correspondence is obtained to provide expressions ...
RESOLUTION‐RETRIEVING SOURCE‐EFFECT COMPENSATION IN HOLOGRAPHY WITH EXTENDED SOURCES
(The American Institute of Physics, 1965-09-15)
Effect of Nuclear Polarization on the Behavior of Solid State Masers
(The American Institute of Physics, 1960-05)
Invariant Imbedding and Case Eigenfunctions
(The American Institute of Physics, 1969-04)
A new approach to the solution of transport problems, based on the ideas introduced into transport theory by Ambarzumian, Chandrasekhar, and Case, is discussed. To simplify the discussion, the restriction to plane geometry ...
Noise in Single‐Crystal Tellurium from Thermal or Optical Excitation
(The American Institute of Physics, 1964-02)
The electrical noise of carefully prepared single‐crystal tellurium samples was measured in the extrinsic temperature range. The effect of temperature variations on the noise power spectrum is interpreted quantitatively ...
Low‐Temperature Heat Capacities and Thermodynamic Functions of Some Platinum and Palladium Group Chalcogenides. I. Monochalcogenides; PtS, PtTe, and PdTe
(The American Institute of Physics, 1961-11)
Heat capacities of platinum monosulfide, platinum monotelluride, and palladium monotelluride were measured in the range 5–350°K. They show the normal sigmoidal temperature dependence with no evidence of transitions or other ...
Spin‐Resonance Properties of Scheelites. I. Vanadium in CaWO4
(The American Institute of Physics, 1968-02-01)
This paper is intended as the first of a series of investigations directed at obtaining information about charge compensation in CaWO4. Vanadium, which lies immediately above niobium in the periodic table, is introduced ...
Wigner Method in Quantum Statistical Mechanics
(The American Institute of Physics, 1967-05)
The Wigner method of transforming quantum‐mechanical operators into their phase‐space analogs is reviewed with applications to scattering theory, as well as to descriptions of the equilibrium and dynamical states of ...
Uranium Monosulfide. The Ferromagnetic Transition. The Heat Capacity and Thermodynamic Properties from 1.5° to 350°K
(The American Institute of Physics, 1968-01-01)
The heat capacity of uranium monosulfide was measured from 1.5° to 22°K by an isothermal (isoperibol) method and from 6° to 350°K by an adiabatic technique. The ferromagnetic transition at 180.1°K has a characteristic ...
Structure of Turbulence in the Boundary Layer near the Wall
(The American Institute of Physics, 1967-09)
Previous measurements of space‐time correlations of turbulent wall pressure and velocity in the boundary layer were extended to include space‐time correlations between the wall pressure and all three velocity components ...
