Energy Transfer in Isotropic Turbulence
(The American Institute of Physics, 1963-08)
Energy transfer from large to small eddies at three stations in turbulence behind a square mesh is determined by measuring the rates of change and viscous dissipation of the spectrum and the results are compared with a ...
CO2‐CS2 Geiger Counter
(The American Institute of Physics, 1961-08)
Experiments on the mechanism and characteristics of a CO2‐CS2 Geiger counter are reported, and circuits and methods of operation which satisfy the special requirements are described. Counter: The active part is 2⅞ in. in ...
Fuel cells--II. Propane and propylene on Adams' platinum catalyst
(Elsevier, 1964-12)
In order to control the quantity of previously adsorbed hydrogen in fuel electrodes to be used with hydrocarbons, the use of Adams' platinum catalyst was investigated. Preferred procedures for electrode preparation were ...
Fluorescence as a source of noise in Q-switched ruby laser atmospheric backscattering experiments
(Elsevier, 1969-06)
Interpretation of the results of atmospheric baekscattering experiments, when using a Q-switched ruby laser as the source of photons, requires consideration of several sources of noise in the statistical analysis. This ...
Configuration Interaction in Two‐ and Three‐Electron Atoms
(The American Institute of Physics, 1966-12-01)
The ground states of the first four members of the helium isoelectronic series and the 22S and 22P states of lithium are calculated using a configuration‐interaction expansion in a complete denumerable set of single‐particle ...
On the viscosity of a fluidized system
(Steinkopff-Verlag; Dr. Dietrich Steinkopff Verlag ; Springer Science+Business Media, 1967-02)
By considering a fluidized state to be similar to a ‘fluid’ with a given density, which depends on the voidage, a rough order of magnitude for the apparent shear viscosity of the ‘fluid’ was found from a simple study of ...
One‐Speed Neutron Transport in Two Adjacent Half‐Spaces
(The American Institute of Physics, 1964-05)
Using Case's method for solving the one‐speed transport equation with isotropic scattering, the Milne problem solution, the solution for a constant source in one half‐space, and the Green's function solution are obtained ...
Analysis of the inelastic scattering of 50 MeV protons
(Elsevier, 1968-09-23)
Differential cross sections and asymmetries for 50 MeV proton scattering from vibrational states in 64,66,68,70Zn and 114Cd have been analysed using a collective-model interaction obtained by deforming the entire optical ...
