FET Operational Amplifiers as Fast Electrometers
(The American Institute of Physics, 1967-09)
Piezoelectric Pressure Transducer with Acoustic Absorbing Rod
(The American Institute of Physics, 1967-06)
A piezoelectric pressure transducer has been designed, using readily available, inexpensive materials, which is capable of measuring sidewall pressures over a wide frequency range without serious distortion of the signal ...
Measurements of Plasma Energy Density and Conductivity from 3 to 120 kbar
(The American Institute of Physics, 1967-01)
Plasma energy density, conductivity, and temperature were measured at various pressures ranging from 3 to 120 kbar. The experimental work was conducted in two parts; plasmas with pressures to 15 kbar were formed by capacitor ...
Orientation‐Averaged Amplitude of the One‐Quantum Term in the Neutron Scattering Law for Molecular Gases
(The American Institute of Physics, 1967-01-15)
The amplitude of the one‐quantum term in the scattering law for coherent scattering of neutrons by molecular gases is calculated using a generating‐function approach. The phase factor exp (iκ⋅b) is averaged jointly with ...
Time‐Dependent Green's Function for a Moving Isotropic Nondispersive Medium
(The American Institute of Physics, 1967-03)
The time‐dependent Green's function for a moving isotropic nondispersive medium is hereby obtained by taking the ω‐integration of the time‐harmonic solution which was previously obtained by means of an operational method ...
Crystal Vibrations of Polyethylene
(The American Institute of Physics, 1967-01-15)
Several problems involving the internal and external vibrations of the polyethylene crystal have been studied. The splittings of some of the internal vibration bands arising from transition dipole coupling have been evaluated ...
Five-dimensional quasi-spin the n, T dependence of shell-model matrix elements in the seniority scheme
(Elsevier, 1967-09-29)
The five-dimensional quasi-spin formalism is used to factor out the n, T dependent parts of shell-model matrix elements in the seniority scheme and derive reduction formulae which make it possible to express matrix elements ...
Voltammetry without background electrolyte: Redox pattern of DPPH in non-aqueous media
(Elsevier, 1967-09)
The voltammetric behaviour of diphenylpicrylhydrazyl (DPPH), a stable organic free radical, which has been found to give reversible reduction waves at platinum in 0[middle dot]1 M NaClO4 solution in acetonitrile, was ...
Weber's Mixed Boundary‐Value Problem in Electrodynamics
(The American Institute of Physics, 1967-03)
Electrodynamics problems with mixed boundary values promise to assume increasing practical importance in fields such as plasma physics. A new method of attacking such problems in three dimensions is presented and discussed.
