Electronic Interaction Integrals for Atoms Calculated with Laguerre Polynomial Radial Wavefunctions
(The American Institute of Physics, 1967-03-01)
Straightforward evaluation of electronic interaction integrals for many‐electron atoms using Laguerre polynomial radial wavefunctions leads to sums of differences of large numbers. An alternate formulation is presented ...
Effect of Transport Properties on Supersonic Expansion around a Corner
(The American Institute of Physics, 1967-05)
The compressible flow of a viscous, heat‐conducting gas around a corner is considered; in particular, the viscous corrections in the expansion region are calculated. The solutions are written in terms of asymptotic expansions, ...
Structure of normal and contracted tail sheaths of T4 bacteriophage
(Elsevier, 1967-07-28)
The structural arrangement of protein subunits in extended and contracted tail sheaths of T4 bacteriophage has been studied by optical diffractometry of electron micrographs. The analysis of such diffraction patterns shows ...
Evidence for Pseudo‐Jahn—Teller Effect in XeF6
(The American Institute of Physics, 1967-06-01)
Triple Resonance Method for Molecular hfs Spectroscopy: Measurements on 133Cs19F
(The American Institute of Physics, 1967-11-15)
Three sequential oscillatory fields are employed in a molecular beam electric resonance spectrometer in order to observe molecular hfs transitions which do not obey the criteria for observability in the usual beam apparatus. ...
ESR Studies of Nitrobenzene, o‐Dinitrobenzene, and m‐Dinitrobenzene Alkali‐Metal Salts
(The American Institute of Physics, 1967-11-01)
The hyperfine splittings for the lithium, sodium, potassium, and cesium salts of nitrobenzene and the sodium, potassium, and cesium salts of o‐dinitrobenzene over a range of temperature in DME are reported, as well as the ...
General Coupling Coefficients for the Group SU(3)
(The American Institute of Physics, 1967-01)
A Hilbert space method, previously applied to the group SU(2), is employed to examine the representations Dλμ and the reduction of the direct‐product representation of the group SU(3). The base vectors ∣λμ;α>, an orthogonal ...
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 ...
