Calculated Scattering Cross Sections for He☒He at Thermal Energies
(The American Institute of Physics, 1964-02-01)
Steady and Unsteady Motions and Wakes of Freely Falling Disks
(The American Institute of Physics, 1964-02)
The motions and wakes of freely falling disks were studied and it was found that the diverse motions of the disks exhibit a systematic dependence on the Reynolds number Re, and the dimensionless moment of inertia I*. The ...
Hydraulic Jump in a Rotating Fluid
(The American Institute of Physics, 1964-05)
A hydraulic jump occurs in a layer of fluid flowing down the inner wall of a rotating cylinder when the downstream conditions are adequate. The theory of these jumps is presented, together with supporting experimental data. ...
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 ...
Reply to the Comments by E. K. Marchildon, A. Clamen, and W. H. Gauvin
(The American Institute of Physics, 1964-12)
Effect of Chemisorbed Oxygen on Photovoltaic and Photoconductive Processes in Rutile
(The American Institute of Physics, 1964-06)
Adsorbed oxygen increases both the response and the response time for the photovoltaic effect in rutile.The model for the effect of chemisorbed oxygen on the photoconductivity has been modified to take into consideration ...
Boundary‐Layer Transition on a Cooled Rough Sphere in Hypersonic Flow
(The American Institute of Physics, 1964-08)
Measurements are given of the combined effects of two‐dimensional roughness and surface cooling on boundary layer transition at 45° from the stagnation point on a sphere in simulated hypersonic flow. With the roughness ...
EPR Spectrometer for Studying Crystals under High Hydrostatic Pressure
(The American Institute of Physics, 1964-07)
A spectrometer for studying the effect of hydrostatic pressure to 10 kbar on the electron paramagnetic resonance spectra of crystals is described. A two‐sample comparison method is used which greatly simplifies both the ...
Liquid—Vapor Equilibrium in the System Equilibrium Hydrogen—Helium
(The American Institute of Physics, 1964-10-15)
Liquid—vapor equilibrium‐phase compositions for the binary system 20.40° equilibrium hydrogen—helium have been determined for six isotherms in the range 20.40°—31.50°K and at pressures up to 500 psia. The vapor recirculation ...
Photoconductivity in Single‐Crystal Tellurium
(The American Institute of Physics, 1964-02)
Measurements of the steady‐state and transient photoconductive behavior in the extrinsic range are presented and interpreted in terms of a simple trapping model. The change of electrical conductivity due to steady irradiation ...
