Stochastic Approach to the Theory of Fluctuations in Plasmas
(The American Institute of Physics, 1968-03)
A stochastic (in contrast to kinetic theoretic) approach to the calculation of correlation functions in fully ionized plasmas is investigated. Formally different results are obtained. The question as to whether or not the ...
Assignment of the 71‐cm−1 Band in Polyethylene
(The American Institute of Physics, 1965-06-01)
Simple Extrusion Die for in vacuo Production and Explosion of Lithium Wires
(The American Institute of Physics, 1969-07)
Semiclassical Analysis of the Extrema in the Velocity Dependence of Total Elastic‐Scattering Cross Sections: Relation to the Bound States
(The American Institute of Physics, 1963-06-01)
The phenomenon of extrema in the velocity dependence of the total elastic cross section Q(v) for atom—atom scattering in the thermal‐energy region is shown to be a quite general one, whenever the interaction potential ...
Molecular Freedom of the Ammonium Ion. Heat Capacity and Thermodynamic Properties of Ammonium Perchlorate from 5°–350°K
(The American Institute of Physics, 1969-06-15)
The heat capacity of NH4ClO4 has been determined by adiabatic calorimetry from 5°–350°K and found to be of simple sigmate character without thermal anomalies. The heat capacity (Cp)(Cp), entropy (S°)(S°), enthalpy function ...
Thermal Properties Based upon Heat Capacity and Decomposition Pressure of Tetramethylammonium Hydrogen Dichloride. Nature of the Hydrogen Bond in the [Cl☒H☒Cl]— Ion
(The American Institute of Physics, 1962-05-15)
The heat capacity of tetramethylammonium hydrogen dichloride was determined from 5° to 350°K by adiabatic calorimetry and the derived thermodynamic properties were calculated. No thermal anomalies were found. Molal values ...
Liquid—Vapor Equilibrium in the System Equilibrium Hydrogen—Helium
(The American Institute of Physics, 1964-10-15)
Liquid—vapor equilibrium‐phase compositions for the binary system 20.40° equilibrium hydrogen—helium have been determined for six isotherms in the range 20.40°—31.50°K and at pressures up to 500 psia. The vapor recirculation ...
Photoconductivity in Single‐Crystal Tellurium
(The American Institute of Physics, 1964-02)
Measurements of the steady‐state and transient photoconductive behavior in the extrinsic range are presented and interpreted in terms of a simple trapping model. The change of electrical conductivity due to steady irradiation ...
Quantum Statistics and Slow Neutron Scattering by Gases
(The American Institute of Physics, 1967-12-15)
A surprisingly simple expression in ``closed form'' for the cross section d2σ/dΩdϵ for the scattering of thermal neutrons (including polarized neutrons) from an ideal quantum gas is derived. This result extends the work ...
