Effect of Chemisorbed Oxygen on Photovoltaic and Photoconductive Processes in Rutile
(The American Institute of Physics, 1964-06)
Adsorbed oxygen increases both the response and the response time for the photovoltaic effect in rutile.The model for the effect of chemisorbed oxygen on the photoconductivity has been modified to take into consideration ...
Extrema in Velocity Dependence of Total Elastic Cross Sections for Atomic Beam Scattering: Relation to Di‐atom Bound States
(The American Institute of Physics, 1962-10-15)
Boundary‐Layer Transition on a Cooled Rough Sphere in Hypersonic Flow
(The American Institute of Physics, 1964-08)
Measurements are given of the combined effects of two‐dimensional roughness and surface cooling on boundary layer transition at 45° from the stagnation point on a sphere in simulated hypersonic flow. With the roughness ...
A 14×14×7‐in. Thin Plate Spark Chamber
(The American Institute of Physics, 1961-05)
A Lucite wall spark chamber with 0.012‐in. aluminum electrodes, active dimensions 14×14×7 in., has been constructed and tested both with cosmic rays and a particle beam. The gap efficiency is nearly 100% and the time ...
Force fields for nitriles
(Elsevier, 1968-11)
A valence force field for nitriles based on the force field obtained for hydrocarbons is found to give very good agreement with the observed bands for several mono- and di-nitrile molecules. The average deviation between ...
Vibrational analysis of chain folding in polyethylene crystals
(John Wiley & Sons, Inc., 1968-05)
The vibration frequencies of a polyethylene crystal lattice have been computed for various structures in which a fully deuterated chain is mixed with a normal chain. Intermolecular potential functions previously developed ...
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 ...
