Energy Transfer in Isotropic Turbulence
(The American Institute of Physics, 1963-08)
Energy transfer from large to small eddies at three stations in turbulence behind a square mesh is determined by measuring the rates of change and viscous dissipation of the spectrum and the results are compared with a ...
The rotation spectrum of methyl alcohol from 20 cm-1 to 80 cm-1
(Elsevier, 1963)
The rotational spectrum of methanol vapor has been measured from 20 cm-1 to 80 cm-1. The observations have been compared with the predictions of Burkhard and Dennison and for the most part good agreement is found. Some ...
Infrared target and background radiometric measurements--concepts units and techniques
(Elsevier, 1963-09)
This report discusses concepts units and techniques for making and describing measurements of radiation from targets and backgrounds.
A restricted class of exact eigenstates of the pairing-force Hamiltonian
(Elsevier, 1963-02-01)
Determination of Barrier Heights from Low‐Temperature Heat‐Capacity Data
(The American Institute of Physics, 1963-09-01)
A method is presented by which barrier heights, in potential functions hindering the internal rotation of methyl groups, or spectroscopically inactive vibrational frequencies, can be obtained solely from thermal data for ...
Application to the exact theory of the pairing model to some even isotopes of lead
(Elsevier, 1963-06-01)
The 23Na(d, p)24Na reaction and the nuclear structure of 24Na
(Elsevier, 1963)
The level scheme of 24Na up to about 7 MeV has been studied with the 23Na(d, p)24Na reaction. Several new levels have been observed. A few discrepancies in energy assignment to levels exist between these and earlier ...
A very-thin walled sample holder for liquids
(Elsevier, 1963)
A sample holder for liquids is described which was developed for use in neutron scattering measurements. The design is very simple and inexpensive to fabricate, yet the walls of the container are very thin, 0.002" aluminum, ...
Velocity of a Fluid Mass Imbedded in Another Fluid Flowing in a Porous Medium
(The American Institute of Physics, 1963-10)
The velocity of a fluid mass imbedded in another fluid, which is of a different viscosity and a different specific weight and flowing in a porous medium under a prevailing uniform pressure gradient, is investigated. The ...
