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 ...
An image intensifier-scintillator device for determination of profiles and images of weak beams of ionizing particles or X-rays
(Elsevier, 1961)
An instrument for determining the shape and intensity distribution of particle and X-ray beams has been developed using an image intensifier tube together with a bundle of filaments of scintillator. A description of the ...
A Closed General Solution of the Probability Distribution Function for Three‐Dimensional Random Walk Processes
(The American Institute of Physics, 1961-02)
A closed general solution of the probability distribution function for three‐dimensional random walk processes is derived. In addition: (1) For the particular case of equal‐length displacements, the exact solution is ...
Quantum Calculations of the Velocity Dependence of the Differential and Total Cross Sections for Elastic Scattering of Molecular Beams
(The American Institute of Physics, 1961-02)
The partial wave treatment (phase shift analysis) of the elastic scattering of molecular beams [J. Chem. Phys. 33, 795 (1960)] is applied to the calculation of the velocity dependence of the differential and total cross ...
Sixth Virial Coefficients for Gases of Parallel Hard Lines, Hard Squares, and Hard Cubes
(The American Institute of Physics, 1961-03)
Variation of Permittivity with Electric Field in Perovskite‐Like Ferroelectrics
(The American Institute of Physics, 1961-05)
A model is considered for the case of polycrystalline ferroelectrics in which each crystallite is presumed to behave according to a free‐energy function of the type formulated by A. F. Devonshire [Advances in Phys. 3, 85 ...
Zone Leveling and Crystal Growth of Peritectic Compounds
(The American Institute of Physics, 1961-03)
Homogeneous samples of peritectic semiconducting compounds have been prepared for optical and electrical characterization by combining zone leveling concepts with Bridgeman crystal growth techniques. Proper temperature ...
Electromagnetic radiation from a source in a plasma
(Elsevier, 1961-11)
The problem of determining the electromagnetic radiations from a given charge-current distribution situated in a plasma in the presence of a uniform external magnetic field is solved. Explicit expressions for the asymptotic ...
Effect of Inert‐Gas Moderators on the (n, γ) Activated Reaction of I128 with CH4
(The American Institute of Physics, 1961-06)
In the presence of a large excess of gaseous methane, 54.4±0.5% of I128 formed by (n, γ) activation was found to become stabilized in organic combination. The effects of inert‐gas additives in moderating the reaction of ...
