Te125 Mossbauer effect study of neutron capture effects in PbTe, Te and TeO2
(Elsevier, 1969-05)
The Mossbauer emission spectra of Te125 in PbTe, Te metal, and TeO2 have been measured following neutron capture in Te124. Mossbauer data for each sample were taken after the source irradiation and following thermal ...
Slanting of a Magnetically Stabilized Electric Arc in Transverse Supersonic Flow
(The American Institute of Physics, 1966-04)
Experimental observations are presented which indicate the existence of a convective interaction mechanism affecting the direction and stability of electric current in a flowing gas. The observations were made of an electric ...
Laser scatter measurements in the mesosphere and above
(Elsevier, 1969-01)
Recent papers by Sandford are discussed in relation to results from an improved optical radar which was in use during the period January-February 1967.
Origins of Characteristic Bands in the Infrared Spectra of Isotactic Polystyrene and Isotactic Poly (Ring‐d5 Styrene)
(The American Institute of Physics, 1961-11)
The origins of characteristic bands in the infrared spectrum of isotactic polystyrene have been studied with the aid of the spectrum of isotactic poly (ring‐d5 styrene). It is found that these bands can be classified into ...
Effect of Chemisorbed Oxygen on Photovoltaic and Photoconductive Processes in Rutile
(The American Institute of Physics, 1964-06)
Adsorbed oxygen increases both the response and the response time for the photovoltaic effect in rutile.The model for the effect of chemisorbed oxygen on the photoconductivity has been modified to take into consideration ...
Calculation of the absorption coefficient for lines with combined Doppler and Lorentz broadening
(Elsevier, 1965)
Methods are described for calculating the spectral absorption coefficient for lines with combined Doppler and Lorentz broadening.
Phonon model description of spherical nuclei
(Elsevier, 1969-08-04)
A completely numerical quadrupole phonon model calculation enables one to obtain a satisfactory description of anharmonic energy levels, reasonable B(E2) ratios and quadrupole moment ratio for even-even spherical nuclei. ...
Extrema in Velocity Dependence of Total Elastic Cross Sections for Atomic Beam Scattering: Relation to Di‐atom Bound States
(The American Institute of Physics, 1962-10-15)
Boundary‐Layer Transition on a Cooled Rough Sphere in Hypersonic Flow
(The American Institute of Physics, 1964-08)
Measurements are given of the combined effects of two‐dimensional roughness and surface cooling on boundary layer transition at 45° from the stagnation point on a sphere in simulated hypersonic flow. With the roughness ...
