Bremsstrahlung of Slow Electrons in Neutral Gases and Free‐Free Absorption of Microwaves
(The American Institute of Physics, 1967-06)
Bremsstrahlung of nonrelativistic electrons in a neutral gas is investigated including the polarization and exchange effects. The intensity and spectrum of the bremsstrahlung and of the induced dipole radiation are obtained ...
Matrix Elements for Configuration d4 in a Weak Octahedral Field Using Racah Methods
(The American Institute of Physics, 1967-11-15)
Employing Racah algebra, the general formula for calculating the matrix elements of a weak crystalline field for configuration dn has been derived. Applying this formula the matrix elements for d4 (including spin—orbit ...
Magnetic Interactions for the Electronic Configuration d5
(The American Institute of Physics, 1967-04-15)
Applying Horie's method, the matrix elements of spin—other‐orbit interaction for configuration d5 have been calculated. The magnetic interaction energy has also been calculated for Mn++ by means of perturbation theory. It ...
Construction of Invariant Scalar Amplitudes without Kinematical Singularities for Arbitrary-Spin Nonzero-Mass Two-Body Scattering Processes
(1967-09-09)
The relativistic transition amplitude for any two-body reaction involving only particles of nonzero mass but arbitrary spin is decomposed in terms of scalar amplitudes that are regular functions in the space of scalar ...
Generation of Giant Pulses from a Neodymium Laser with an Organic‐Dye Saturable Filter
(The American Institute of Physics, 1967-04)
There has been much recent interest in the production of high‐peak power laser pulses by regeneration switching. Organic dyes have been used as saturable filters for both the ruby (cyanine dyes) and neodymium (a polymethine ...
Intensity Fluctuations of the Radiation from a Dispersive Blackbody
(The American Institute of Physics, 1967-12)
Statistical properties of the output fluctuations of a photon detector measuring the intensity of radiation at a given frequency emitted by a dispersive blackbody are investigated using Langevin's technique. The variance‐to‐mean ...
Linewidth Variations in ESR Spectra of o‐Dinitrobenzene Radicals
(The American Institute of Physics, 1967-05-15)
A force field for secondary chlorides
(Elsevier, 1967-08)
A force field has been derived for monochloro- and 2,4-dichloro-hydrocarbons. The Snyder-Schachtschneider force field for hydrocarbons was used as a starting point, the constants associated with the secondary chlorine being ...
Benzene Vibrational Exciton Spectrum
(The American Institute of Physics, 1967-11-01)
A critical discussion of the infrared polarization assignments of Zwerdling and Halford, in view of the now accepted benzene crystal structure, leads to acceptance of their results, though with somewhat reduced credibility. ...
