Magnetohydrodynamics at Small Magnetic Reynolds Numbers
(The American Institute of Physics, 1962-04)
Two problems are considered, each of which represents a class of flows. In the first problem the motion is induced by passage of electric current through an incompressible viscous electrically conducting fluid contained ...
Axial Quasi‐Brillouin Streams
(The American Institute of Physics, 1962-07)
A nonlaminar model for axially uniform electron streams is postulated and conditions for which the model is consistent with physical requirements are derived. The character of the current density profiles permitted by the ...
Sixth and Seventh Virial Coefficients for the Parallel Hard‐Cube Model
(The American Institute of Physics, 1962-06-15)
A procedure for calculating virial coefficients for parallel hard lines, squares, and cubes is outlined, and the sixth and seventh virial coefficients are computed for these models. The essential step in the evaluation of ...
Semiclassical Equivalence Relationship Applied to the Calculation of Molecular‐Beam Scattering Phase Shifts
(The American Institute of Physics, 1962-03-01)
Use of a Large Thermocouple Junction to Locate Temperature Disturbances
(The American Institute of Physics, 1962-03)
A temperature disturbance within a large thermocouple junction produces a voltage which decreases with distance from the disturbance. Resulting voltage residues can be compared at two or more points on the junction to ...
Failure to Bond Rupture and Nuclear Recoil Following (n, γ) Activation
(The American Institute of Physics, 1962-02-15)
Following the absorption of a thermal neutron by 127I or 79Br, the neutron‐binding energy is frequently released in the form of a gamma‐ray cascade. As a result of partial cancellation of gamma‐ray momenta, a small fraction ...
Green's Distributions and the Cauchy Problem for the Multi‐Mass Klein‐Gordon Operator
(The American Institute of Physics, 1962-11)
Explicit forms of the Green's functions (which are to be regarded as distributions in the sense of Schwartz) for the multi‐mass Klein‐Gordon operator in n‐dimensional spaces are presented. The homogeneous Green's functions ...
Velocity Dependence of the Differential Cross Sections for the Scattering of Atomic Beams of K and Cs by Hg
(The American Institute of Physics, 1962-11-01)
Measurements of the velocity dependence of the angular intensity distribution of potassium and cesium beams scattered by a crossed beam of mercury are presented. The alkali beam was velocity selected, with a triangular ...
Reactions of High‐Energy, Excited I128 Ions with Gaseous Molecules
(The American Institute of Physics, 1962-01-15)
The manner in which molecular additives inhibit the reaction of (n, γ) activated I128 with CH4 was determined in an effort to observe indirectly reactions of I128 with the additives. The data suggest that (1) O2, N2, and ...
