Laminar Free‐Convection Heat Transfer from a Needle
(The American Institute of Physics, 1969-02)
The partial differential equations for laminar free convection over a needle are reduced to ordinary differential equations by a similarity analysis, and the values of local skin friction, heat transfer for various needles ...
Influence of defects on the infrared spectra of polymers Presented in part at the Symposium on Spectroscopy of Polymers, American Chemical Society, Chicago, September 1967.
(John Wiley & Sons, Inc., 1969-01)
For an infinitely repeated regular polymer chain structure the only vibrations which are optically active are those in which the phase of the motion is the same in each unit (the factor-group modes). Frequencies for which ...
Leading Edge of a Shock‐Induced Boundary Layer
(The American Institute of Physics, 1962-10)
The boundary layer which is formed as a shock wave propagates down a shock tube causes both shock attenuation and shock curvature. Hartunian studied the curvature effect; however, as he points out, because of the singularities ...
A model of CP violation
(Elsevier, 1969-12-08)
A model of the weak interactions mediated by a nonet or an octet of W-mesons is presented. The model contains the CP violating phase intrinsically.
Flow Fields of Flame Propagating in Channels Based on the Source Sheet Approximation
(The American Institute of Physics, 1963-08)
A volume source sheet plus a uniform flow is used to represent the flow field of a flame propagating in a channel. The unknown flame shape is determined by the requirement that the velocity normal and relative to it, i. ...
Generation of Giant Pulses from a Neodymium Laser with an Organic‐Dye Saturable Filter
(The American Institute of Physics, 1967-04)
There has been much recent interest in the production of high‐peak power laser pulses by regeneration switching. Organic dyes have been used as saturable filters for both the ruby (cyanine dyes) and neodymium (a polymethine ...
Quantum Mechanical (Phase Shift) Analysis of Differential Elastic Scattering of Molecular Beams
(The American Institute of Physics, 1960-09)
For a spherically symmetrical intermolecular potential V(r)=ϵf(r/σ) the quantum calculation of the elastic scattering cross section dσ(Θ)/dΩ in the c.m. system is carried out as follows. For a given relative velocity (or ...
Production of a 23S Helium Beam
(The American Institute of Physics, 1969-09)
Beams of metastable helium produced by electron bombardment generally contain atoms in both the 21S and 23S states. It is important in many experiments to distinguish between these states, or at least to know the population ...
Vibration-rotation energies of tetrahedral XY4 molecules : Part II. The fundamental [nu]3 of CH4
(Elsevier, 1961)
The matrix elements derived in the first paper of this series are used to compute the frequencies of the tetrahedral fine structure components of the rotational lines of the fundamental [nu]3 of CH4. The theoretically ...
