Analytic Expressions Relating Surface Charge and Potential Profiles in the Space‐Charge Region in Semiconductors
(The American Institute of Physics, 1963-09)
The potential on the surface of a semiconductor is formulated analytically as a function of surface charge concentration by a double integration of Poisson's equation in one‐dimensional form. All combinations of the types ...
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 ...
Dual Role of Viscosity in the Instability of Revolving Fluids of Variable Density
(The American Institute of Physics, 1961-07)
The stability of a viscous fluid between rotating cylinders and with a radial temperature gradient against the formation of axisymmetric disturbances (Taylor vortices) is considered, and it has been found that viscosity ...
TIME AVERAGE HOLOGRAPHY EXTENDED
(The American Institute of Physics, 1969-01-01)
It is demonstrated that the usefulness of time‐average holography in analyzing vibration can be extended by modulating the reference beam.
Characteristic infrared frequencies of rotational isomers of alkyl chlorides
(Elsevier, 1962)
A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond. ...
Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
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 ...
Single Mode Output with the Spectra‐Physics Model 125 He☒Ne Laser
(The American Institute of Physics, 1969-10)
The Most General Clebsch‐Gordan Coefficients of the Universal Covering Group of the Inhomogeneous Lorentz Group
(The American Institute of Physics, 1966-06)
The most general Clebsch‐Gordan coefficients to reduce the physically most important n‐fold product representations of the groups P+↑ and P (Universal covering groups of the restricted and full inhomogemeous Lorentz groups) ...
