Hydrodynamic Analysis of Noise in a Finite‐Temperature Electron Beam
(The American Institute of Physics, 1965-08)
On the basis of a small‐signal, one‐dimensional analysis, a set of basic macroscopic differential equations, governing the fluctuations in quantities such as the electron‐beam temperature, the mean velocity, and the current ...
Iterative Method for Solution of the One‐Dimensional Wave Equation: Eigenvalues and Eigenfunctions for L‐J (12, 6) and Exponential (α, 6) Interatomic Potentials
(The American Institute of Physics, 1963-05-01)
A method of direct numerical integration of the one‐dimensional wave equation is described and illustrated by calculations of the radial wavefunctions, vibrational energy levels, and numbers of bound states for diatomic ...
Structure of Weak Non‐Hugoniot Shocks
(The American Institute of Physics, 1963-05)
As the curvature of shock waves increases, the shock structure becomes two dimensional, and the usual Hugoniot jump conditions no longer hold. An equation has been derived for the structure of such a two‐dimensional ...
High‐Velocity Molecular Beam Scattering: Total Elastic Cross Sections for L‐J(n, 6) and Exp‐6(α) Potentials
(The American Institute of Physics, 1963-01-15)
Explicit expressions are derived for the total elastic scattering cross sections in the high‐velocity region for molecules interacting according to L‐J (n, 6) and exp‐6(α) potentials. Cross sections are presented in tabular ...
Intensity Fluctuations of the Radiation from a Dispersive Blackbody
(The American Institute of Physics, 1967-12)
Statistical properties of the output fluctuations of a photon detector measuring the intensity of radiation at a given frequency emitted by a dispersive blackbody are investigated using Langevin's technique. The variance‐to‐mean ...
Reply to the Comments by E. K. Marchildon, A. Clamen, and W. H. Gauvin
(The American Institute of Physics, 1964-12)
COLOR HOLOGRAMS FOR WHITE LIGHT RECONSTRUCTION
(The American Institute of Physics, 1966-06-01)
Second Virial Coefficient for the Spherical Shell Potential
(The American Institute of Physics, 1962-02-15)
Values of the second virial coefficient for the three‐parameter spherical shell potential are tabulated over wide ranges of temperature and shell size. The potential, which is not new, results from the interaction of two ...
The vibration-rotation energies of tetrahedral XY4 molecules : Part I. Theory of spherical top molecules
(Elsevier, 1961)
The theory of vibration-rotational perturbations in tetrahedral XY4 molecules has been reexamined in the light of the modern theory of angular momentum coupling. It is shown that, even to third order of approximation, the ...
Lattice‐Frequency Studies of Crystalline and Fold Structure in Polyethylene
(The American Institute of Physics, 1968-10)
The assignment of the 71 cm−1 band in the infrared spectrum of polyethylene to the B1u translational lattice vibration has been confirmed by dichroism studies on an a‐axis oriented sample. This permits confident use of the ...
