Instability of a Current‐Carrying Fluid Jet Issuing from a Nozzle
(The American Institute of Physics, 1963-09)
The velocity across a jet becomes nonuniform due to contraction or expansion of fluid in the presence of electric current within the nozzle from which it issues. The results obtained elsewhere on the instability of a jet ...
Effect of Electromagnetic Propagation on the Magnetostatic Modes
(The American Institute of Physics, 1963-09)
The second‐order effect of electromagnetic propagation on the essentially static‐field distribution of the magnetostatic modes of a ferromagnetic sample is obtained by an iteration‐type technique. The magnetostatic potential ...
Absorption and Emission Spectrum of CaF2:U3+ from 2.1 to 2.5 Microns
(The American Institute of Physics, 1963-12-01)
The emission and absorption of CaF2:U3+ has been scanned at 77° and 4.2°K and linewidths have been measured. The spectrum is interpreted as arising from ions perturbed by a weak tetragonal crystal field. Preliminary results ...
Microstructure of Thin Single Crystals of Copper
(The American Institute of Physics, 1963-04)
Single‐crystal films of copper of 700–800 Å thickness have been prepared showing high densities of wide stacking faults. Variations in the annealing treatment of the films affect the nature of the imperfections occurring ...
The decay of Ge77
(Elsevier, 1963)
Directional correlation and polarization-direction correlation measurements have been done on gamma rays following the decay of Ge77. The results are found to be consistent with previous spin assignments and a spin of can ...
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)
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 ...
Flow Fields of Flame Propagating in Channels Based on the Source Sheet Approximation
(The American Institute of Physics, 1963-08)
A volume source sheet plus a uniform flow is used to represent the flow field of a flame propagating in a channel. The unknown flame shape is determined by the requirement that the velocity normal and relative to it, i. ...
