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. ...
Modified slater integrals for an ion in a solid
(Elsevier, 1967-05-22)
Expressions for the Slater integrals are derived for an ion of the first transition series when placed in a solid. Reasonable agreement is obtained with experimental data for Co++ in spinel.
On the viscosity of a fluidized system
(Steinkopff-Verlag; Dr. Dietrich Steinkopff Verlag ; Springer Science+Business Media, 1967-02)
By considering a fluidized state to be similar to a ‘fluid’ with a given density, which depends on the voidage, a rough order of magnitude for the apparent shear viscosity of the ‘fluid’ was found from a simple study of ...
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.
Extended detectors in neutron time-of-flight diffraction experiments
(Elsevier, 1967-01-03)
Shell-model calculation in 24Mg
(Elsevier, 1967-03-06)
A shell-model calculation is performed for 24Mg assuming wave functions with maximum symmetry in the spacial coordinates. Several interactions have been used including the Kallio-Kolltveit hard-core potential. A reasonable ...
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 ...
