Simulation of Condensed‐Explosive Detonation Phenomena with Gases
(The American Institute of Physics, 1962-02)
The detonation of a condensed explosive within a solid container and the detonation of a gaseous explosive within an inert‐gas boundary are found to be hydrodynamically similar situations. Experiments with hydrogen, methane, ...
Half‐Space Multigroup Transport Theory
(The American Institute of Physics, 1969-12)
A method for solving various half‐space multigroup transport problems for the case of a symmetric transfer matrix is explained. This method is based on the full‐range completeness and orthogonality properties of the ...
Transport of Noise at Microwave Frequencies through a Space‐Charge‐Limited Diode
(The American Institute of Physics, 1960-06)
Several analyses of the transport of cathode shot noise through a space‐charge‐limited diode at microwave frequencies have been published to date. Each of these analyses has been beset by inconsistencies arising from ...
Heat Capacities and Thermodynamic Properties of Two Tetramethylammonium Halides
(The American Institute of Physics, 1962-05-01)
Heat capacities of tetramethylammonium chloride and bromide were determined by low‐temperature adiabatic calorimetry from 5° to 350°K. Derived thermodynamic properties were then calculated. Two transitions were found in ...
Existence and Uniqueness Theorems for the Neutron Transport Equation
(The American Institute of Physics, 1963-11)
In an attempt to understand the conditions under which the neutron transport equation has solutions, and the properties of those solutions, a number of existence and uniqueness theorems are proved. One finds that the ...
The application of thin-plate spark chambers to high-energy [pi]-p experiments
(Elsevier, 1963-01)
Time‐Dependent One‐Speed Albedo Problem for a Semi‐Infinite Medium
(The American Institute of Physics, 1965-07)
A Laplace transformation technique is used to determine the neutron distribution in a semi‐infinite medium which has been irradiated by a neutron pulse. The result is given in terms of known solutions of Milne's problem ...
Sphere Drag in Flows of Almost‐Free Molecules
(The American Institute of Physics, 1965-05)
A kinetic theory of sphere drag in the transition flows, based on the Boltzmann equation for the Maxwellian molecules, is presented. The exact binary collision integral, in the first order Knudsen iteration, is expanded ...
Analytic Expressions Relating Surface Charge and Potential Profiles in the Space‐Charge Region in Semiconductors
(The American Institute of Physics, 1963-09)
The potential on the surface of a semiconductor is formulated analytically as a function of surface charge concentration by a double integration of Poisson's equation in one‐dimensional form. All combinations of the types ...
Matrix Elements for Configuration d4 in a Weak Octahedral Field Using Racah Methods
(The American Institute of Physics, 1967-11-15)
Employing Racah algebra, the general formula for calculating the matrix elements of a weak crystalline field for configuration dn has been derived. Applying this formula the matrix elements for d4 (including spin—orbit ...
