SU3 recoupling and fractional parentage in the 2s-1d shell
(Elsevier, 1965-02)
Explicit algebraic expressions have been calculated for both the SU3 Wigner coefficients and the SU3 Racah coefficients which are of particular interest in the recoupling problem involving 2s-1d shell nucleons and basis ...
Internal‐Rotation in Hydrogen Peroxide: The Far‐Infrared Spectrum and the Determination of the Hindering Potential
(The American Institute of Physics, 1965-03-15)
The torsional oscillation between the two OH groups of the hydrogen peroxide molecule is investigated through a study of the far‐infrared absorption spectrum of the molecule. A 1‐m‐focal‐length vacuum grating monochromator ...
Superhyperfine Structures in ESR and ENDOR of Cubic CdTe:Mn2+
(The American Institute of Physics, 1965-01-01)
Superhyperfine structure tensors for the 12 next‐nearest ligands in CdTe:Mn2+ have been expressed in terms of molecular orbital and geometry parameters. ESR and ENDOR transition frequencies are related to the superhyperfine ...
Simultaneous Determination of f Values and Vapor Pressures from Optical Absorption Measurements
(The American Institute of Physics, 1965-01-15)
A method for determining both the f value of an absorption line and the vapor pressure of the absorbing atoms exclusively from optical absorption measurements is defined and discussed. The method depends on making absorption ...
Half‐Space Neutron Transport with Linearly Anisotropic Scattering
(The American Institute of Physics, 1965-12)
The method developed by Case is used to solve four time‐independent, one‐speed problems for neutron transport in a homogeneous medium where the scattering function is linear in the cosine of the scattering angle. The ...
Mechanism of Superhyperfine Structure in SnO2:V4+
(The American Institute of Physics, 1965-01-01)
Molecular orbital theory has been applied to SnO2:V4+ to account for the large and small superhyperfine structure observed by From et al. The unpaired spin density at the next‐nearest ligand tin nucleus is formulated. The ...
Polyethylene Frequency Spectrum from ``Warm''‐Neutron Scattering
(The American Institute of Physics, 1965-06-15)
HOLOGRAPHY WITH SPATIALLY NONCOHERENT LIGHT
(The American Institute of Physics, 1965-11-01)
Enhancement of Plasma Density in an Arc Discharge
(The American Institute of Physics, 1965-11)
The amplification or generation of coherent signals by electron‐beam—plasma interactions requires the creation of a high‐density stable plasma. A plasma density of approximately 1015 particles∕cm3 is required to produce a ...
Motion of a Sphere in a Rotating Fluid at Small Reynolds Numbers
(The American Institute of Physics, 1965-04)
The slow steady rise of a solid sphere along the axis of a uniformly rotating viscous liquid is studied when the Reynolds number, based on the translational velocity along the axis of rotation, is less than unity. The ...
