Influence of Rotational Levels on Slow‐Neutron Scattering by Linear Gases
(The American Institute of Physics, 1967-01-01)
Calculations of slow‐neutron partial differential scattering cross sections are reported for molecules with linear symmetry in which the quantum‐mechanical nature of the rotational levels is taken explicitly into account. ...
Energy‐Moment Methods in Quantum Mechanics
(The American Institute of Physics, 1967-10-15)
Three quantum‐mechanical computational techniques based on energy moments, μk = ∫ dqψ*(q)Hkψ(q)μk=∫dqψ*(q)Hkψ(q), and semimoments, νk(q′) = [Hkψ(q)]q = q′νk(q′)=[Hkψ(q)]q=q′, are formulated. The μ method, which employs the ...
Recoupling Coefficients for the Group SU(3)
(The American Institute of Physics, 1967-01)
The Hilbert space method, employed in the previous article to obtain the coupling coefficients of SU(3), is used here to obtain the recoupling, or 6(λμ), coefficients of SU(3). The coefficients are formulated in terms of ...
Wave Excitation in Compressible Plasma and Equivalence Relations
(The American Institute of Physics, 1967-11)
A general, unified solution of the wave excitation due to electric‐current sources, magnetic‐current sources, fluid‐flux sources, and mechanical‐body sources in a compressible plasma which may be anisotropic and inhomogeneous ...
Closure Relations for the Eigenfunctions of the One‐Speed Transport Equation
(The American Institute of Physics, 1967-04)
Orthogonality relations for the eigenfunctions of the one‐speed transport equation are used to derive the corresponding closure relations. These express in a concise form the completeness properties previously proved by Case.
Oblique Incidence of an Electromagnetic Wave on Plasma Half‐Space
(The American Institute of Physics, 1967-03)
A radio frequency electromagnetic wave, polarized in the plane of incidence is incident obliquely upon a plasma half‐space, where the equilibrium plasma is taken to be homogeneous and isotropic. Employing the specular ...
ESR of Alkali Metal Dinitrobenzene Salts in Dimethoxyethane DME
(The American Institute of Physics, 1967-01-01)
Relativistic Effects in Chemical Bonding: The H2+ Molecule
(The American Institute of Physics, 1967-04-01)
The behavior of the electron in the ground state of the hydrogen molecular ion is examined using the Dirac theory. Since the resulting set of equations is not readily separable, the variational theorem is applied to obtain ...
Molecular Beam Measurement of the Hyperfine Structure of 133Cs19F
(The American Institute of Physics, 1967-11-15)
The magnitudes and signs of the hyperfine interaction constants for 133Cs19F in the J = 1, v = 0, 1, 2 states have been measured with a molecular beam electric resonance spectrometer. The results for v = 0 are: eQ1q1 = ...
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 ...
