Stability of Liquid Flow down an Inclined Plane
(The American Institute of Physics, 1963-03)
The stability of a liquid layer flowing down an inclined plane is investigated. A new perturbation method is used to furnish information regarding stability of surface waves for three cases: the case of small wavenumbers, ...
The sign of charge carriers in luminescent transitions
(Kluwer Academic Publishers; Czechoslovak Academy of Sciences ; Springer Science+Business Media, 1963-02)
A thorough treatment of the luminescent mechanisms in high resistivity semiconductors (up to 10 12 ohm cm), has as yet not been satisfactorily established. This is due to the lack of data as is provided by the Hall effect. ...
Useful identities for half-space problems in linear transport theory
(Elsevier, 1963-02)
A typical translationally invariant linear transport problem for a half-space is solved by the eigenfunction method. Using some derived identities for the solution of the associated homogeneous Hilbert problem it is shown ...
Comparison and Appraisal of Approximation Formulas for Total Elastic Molecular Scattering Cross Sections
(The American Institute of Physics, 1963-05-15)
The Massey—Mohr (MM), Schiff (S), and Landau—Lifshitz (LL) approximations for the total elastic cross section (Q) are intercompared. All can be shown to follow from the same assumption, (i.e., the classical small‐angle ...
Electronic Bases of Molecular Vibrations. I. General Theory for Diatomic Molecules
(The American Institute of Physics, 1963-12-01)
The force constant of a diatomic molecule in a given electronic state is the second derivative with respect to the internuclear distance R of the molecular electronic energy, evaluated at the equilibrium distance Re. In ...
Gamma-ray transitions in 32S following proton capture by 31P
(Elsevier, 1963)
Gamma-ray spectra, angular distributions and coincidence spectra have been studied in the reaction 31P(p, [gamma]) 32S at bombarding energies of 355, 440 and 540 keV. Several cascades have been identified and branching ...
Systematics of defect structures in glasses with ionic substitutions
(Elsevier, 1963-08)
The effects of various ionic substitutions on defect structures in glass were investigated in soda-lime-silica systems. It is shown that detailed measurements of flaw characteristics provide a useful tool for investigating ...
The Ca40(d, [alpha])K38 reaction and the nuclear structure of K38
(Elsevier, 1963)
Natural Ca-targets were bombarbarded with 7.7 MeV deutereons. Magnetic analysis was used to obtain [alpha]-particle spectra at angles of 50[deg], 70[deg] and 90[deg]. About 35 levels in K38 were found up to an excitation ...
