Characteristics of Rotationally Stabilized Long Plasma Arcs in a Chamber
(The American Institute of Physics, 1969-08)
An analytical method is developed to determine the gas temperature distribution and the electric field strength‐arc length characteristics of a rotationally stabilized long plasma arc in a cylindrical chamber. The application ...
Improved Slotted Disk Type Velocity Selector for Molecular Beams
(The American Institute of Physics, 1960-08)
A slotted disk type mechanical velocity selector, 10 cm long and 16 cm in diameter, consisting of six disks has been constructed and tested. The velocity resolution corresponding to the half‐intensity width is 0.047; no ...
EPR Spectrometer for Studying Crystals under High Hydrostatic Pressure
(The American Institute of Physics, 1964-07)
A spectrometer for studying the effect of hydrostatic pressure to 10 kbar on the electron paramagnetic resonance spectra of crystals is described. A two‐sample comparison method is used which greatly simplifies both the ...
Low‐Level Linear Microsecond Gate
(The American Institute of Physics, 1961-01)
A linear transmission gate for use in scintillation counter coincidence experiments is described. The gate is suitable for negative pulses of microsecond duration and is linear over a range of 0.01 to 5 v. The circuit is ...
Differential‐Operator Approximations to the Linear Boltzmann Equation
(The American Institute of Physics, 1960-09)
A measure of deviation from equilibrium of an ensemble of particles is proposed, which is physically appropriate and of especially simple form when expressed in terms of the expansion coefficients of the ensemble distribution ...
Linewidth Variations in ESR Spectra of o‐Dinitrobenzene Radicals
(The American Institute of Physics, 1967-05-15)
Hyperfine Structure of Thallium Chloride
(The American Institute of Physics, 1969-03-01)
The radio‐frequency spectra of TlCl at very weak electric and magnetic fields have been measured with a molecular beam electric resonance spectrometer. From these spectra the hyperfine interaction constants for the four ...
A force field for secondary chlorides
(Elsevier, 1967-08)
A force field has been derived for monochloro- and 2,4-dichloro-hydrocarbons. The Snyder-Schachtschneider force field for hydrocarbons was used as a starting point, the constants associated with the secondary chlorine being ...
Tetrahedral approximation in normal coordinate calculations of high polymers
(Elsevier, 1965-06)
Exploding Wire System with in Vacuo Preparation of Lithium Wire
(The American Institute of Physics, 1968-09)
