On the Unit Cell Group and Factor Group in the Theory of the Electronic and Vibrational Spectra of Crystals
(The American Institute of Physics, 1971-10-01)
Inelastic Proton‐Proton Scattering at Very High Energy
(The American Institute of Physics, 1971-01-01)
Electron mobility variation in dense 4He gas
(Elsevier, 1971-05-17)
We present electron mobility measurements in 4He gas for 1019 22 cm-3 and 3 T < 300 K. The results are discussed in terms of current theories and a new model for the electron bubble is proposed.
Production of Polydisperse Sprays
(The American Institute of Physics, 1971-11)
A device which produces a spray with a controllable drop size distribution is described. This system is especially well suited for generating nonsmooth (e.g., bimodal) distributions, although smooth distributions can also ...
Crystal Structure Refinement of SrMoO4, SrWO4, CaMoO4, and BaWO4 by Neutron Diffraction
(The American Institute of Physics, 1971-08-01)
The crystal structures of CaMoO4, SrMoO4, SrWO4, and BaWO4 have been refined from neutron diffraction data taken in the (h0l)(h0l) and (hhl)(hhl) zones. Oxygen position refinement is started from the parameters proposed ...
Radial Expansion of 3d3d Orbitals and the Near Degeneracy of the 4A1g4A1g and 4Eg4Eg Excited States of Octahedral Mn(II) Complexes
(The American Institute of Physics, 1971-07-01)
The relationship between the wavefunctions for mostly 3d3d molecular orbitals and the energies of the nearly degenerate 4A1g4A1g and 4Eg4Eg excited states of octahedral Mn2+ complexes is investigated from two points of ...
Effect of the Temperature Gradient on the Drift Instabilities in a High‐β Collisionless Plasma
(The American Institute of Physics, 1971-09)
The effect of temperature gradient on the drift instabilities in an inhomogeneous high‐β plasma is discussed. The analysis shows that in the presence of a temperature‐gradient, ion‐acoustic, and Alfvénic instabilities can ...
Low‐Energy Neutron Scattering from Hydrogen Chloride
(The American Institute of Physics, 1971-06-15)
Measured double differential cross sections are reported for low‐energy neutron scattering by gaseous hydrogen chloride. Comparison of these data against a calculation based on a quantum mechanical treatment of rotations ...
Muon energy losses and straggling for high energy muons
(Elsevier, 1971-03-15)
The non-Gaussian nature of energy loss straggling is examined. At NAL large muon shields must be designed to reduce flux by about a factor of 1012. Fortunately it is shown here that on the long range end, the straggling ...
Emission of Microwave Noise Radiation From InSb
(The American Institute of Physics, 1971-01)
Low‐field 10‐GHz noise radiation and attendant rf current oscillations are generated in 10‐mm‐long specimens of n‐type InSb at 77°K. Using a special experimental arrangement, both the azimuthal and the polar orientation ...
