Determination of spectra from pulse-height data
(Elsevier, 1975-04-15)
A method for determining parameters of a physical spectrum from pulse-height data is described. This method is designed to utilize information from the entire range of data and possesses advantages over other methods in ...
Electrostatic screening
(The American Institute of Physics, 1975-02)
Using the methods of partial differential equations and functional analysis, we investigate the electric field in the presence of a screen composed of wires of radius r spaced at distance R spread over a surface S. In the ...
Absorption of CO2 laser radiation in an exploded lithium wire plasma
(The American Institute of Physics, 1975-06)
An absorption experiment was performed with a pulsed TEA CO2 laser incident upon a partially ionized plasma created by exploding a 0.0025‐cm‐diam lithium wire in vacuum. Stark broadening of the Li I 6104‐Å line and line ...
Analysis of optical propagation in thick holographic gratings
(Springer-Verlag, 1975-05)
A method of analyzing optical propagation in thick holographic gratings by decomposition of the thick material into thin gratings is discussed. The method is readily applicable to study propagation in multiple gratings of ...
Nature of the surface compounds and reactions observed on graphite electrodes
(Elsevier, 1975-09)
The nature and composition of the surface of pyrolytic graphite and the consequent possible effects, when the material is used as an electrode, are considered on the basis of the structure of the graphite and of the handling ...
Parity nonconservation in the hydrogen atom
(Elsevier, 1975-10-13)
We investigate the possibility of observing parity nonconservation with a metastable hydrogen atom beam, by analyzing two effects which should permit detection of the 2S-2P admixture predicted by the Weinberg model.
Laser heating of a dense plasma pinch
(The American Institute of Physics, 1975-03)
A single fluid, two−temperature, one−dimensional magnetohydrodynamic model has been developed to describe the properties of a linear pinch plasma heated by an axially directed laser beam. The coupling of the laser light ...
Two‐point characteristic function for the Kepler–Coulomb problem
(The American Institute of Physics, 1975-10)
Hamilton’s two‐point characteristic function S (q2t2,q1t1) designates the extremum value of the action integral between two space–time points. It is thus a solution of the Hamilton–Jacobi equation in two sets of variables ...
The 208Pb([alpha], 3He)209Pb reaction at 58 MeV
(Elsevier, 1975-08-04)
The 208Pb([alpha], 3He)209Pb reaction at 58 MeV has been used to search for high-spin states in 209Pb. Only three levels are excited with appreciable intensity: the ground state and levels at . The angular distributions ...
