Neutron-nuclei total cross sections at 27 GeV/c
(Elsevier, 1968-08-05)
The total cross sections for 27 GeV/c neutrons on eight heavy elements, Be through U, has been measured and found to obey the empirical relationship [sigma]T = 48A0.75mb.
Stability of a Horizontal Fluid Interface in a Periodic Vertical Electric Field
(The American Institute of Physics, 1968-07)
The stability of the interface in the presence of a periodic electric field is considered. It is shown that the stability is governed by a Mathieu equation, that the interface can be unstable even if the electric field is ...
Coulomb displacement energies in the shell
(Elsevier, 1968-06-24)
The experimental Coulomb displacement energies in the shell (except one) can be described by Hecht's Coulomb energy equation with a standard deviation of 8.5 keV if it is assumed that the Coulomb interaction radius is ...
Energy Expectation Values and the Integral Hellmann–Feynman Theorem: H2+ Molecule
(The American Institute of Physics, 1968-08-01)
It is by now well known that the integral Hellmann–Feynman (IHF) theorem has little quantitative utility for chemically interesting problems, although the formalism potentially affords a ready physical interpretation of ...
Use of a Linear Staircase Generator in Displaying Synchronized Pulse Activity
(The American Institute of Physics, 1968-09)
Dynamics of Bubbles Moving in Liquids with Pressure Gradient
(The American Institute of Physics, 1968-06)
The time history of the velocity, size, and deformation of a bubble moving in the flow field around a point source or sink is studied analytically. Consideration is given to the case where the changes in the bubble velocity, ...
Comment on “Oblique Incidence of an Electromagnetic Wave on a Plasma Layer”
(The American Institute of Physics, 1968-12)
Small 10 kG Pulsed Magnet
(The American Institute of Physics, 1968-11)
A small magnet pulsed at 2000 cps is described. The method of construction by interlacing spirals of Teflon and copper is discussed. The field produced is through a volume of approximately 1 cc. The total volume of the ...
Free Convection in a Rotating Medium
(The American Institute of Physics, 1968-09)
Numerical techniques have been used to study natural convection in a fluid subjected to axial rotation. Axisymmetrical flows were studied in two different geometries for a variety of rotational speeds. For case I (R1 = ...
Molecular Structure of XeF6. II. Internal Motion and Mean Geometry Deduced by Electron Diffraction
(The American Institute of Physics, 1968-03-15)
The distribution of internuclear distances in gaseous XeF6 exhibits unusually diffuse XeF6 bonded and F–F geminal nonbonded peaks, the latter of which is severely skewed. The distribution proves the molecule cannot be a ...
