Reflection of Plane‐Polarized, Electromagnetic Radiation from an Echelette Diffraction Grating
(The American Institute of Physics, 1957-02)
A variational method is used to calculate the distribution of energy reflected from an echelette diffraction grating. Experiments performed using a klystron generating 3.2‐cm electromagnetic waves which impinge upon a large ...
Medium‐Energy Neutron Time‐of‐Flight Spectrometer
(The American Institute of Physics, 1957-04)
A neutron time‐of‐flight spectrometer developed for the 1‐ to 20‐Mev region is described. The instrument makes use of the phase bunching of deuterons in the Michigan 42‐inch cyclotron and an external beam pulsing system ...
Integrating Attachment for the Weissenberg Camera
(The American Institute of Physics, 1957-05)
Effect of Magnetic Field on Coupled Helix Attenuators
(The American Institute of Physics, 1957-11)
Low temperature heat capacity and thermodynamic properties of zinc ferrite
(Elsevier, 1957)
The heat capacity of zinc ferrite (ZnFe2O4) has been determined over the range 5 to 350[deg]K. Molal values of Cp,S0, and H0-H00 computed from the thermal data are 32.99+/-0.03 cal/deg., 36[middle dot]01 +/-0[middle dot]03 ...
Raman Spectrum and Vibrational Assignments of Gaseous Dimethyl Ether
(The American Institute of Physics, 1957-01)
The Raman spectrum of gaseous dimethyl ether has been obtained and that of the liquid reinvestigated. In the low‐frequency region of the gas spectrum, two bands have been observed which are attributed to overtones of the ...
Errata : Raman Spectra, Vibrational Assignments, and Force Constants for BH3CO and BD3CO
(The American Institute of Physics, 1957-10)
Measurements of the Mobilities of the Negative Ions in Oxygen and in Mixtures of Oxygen with the Noble Gases, Hydrogen, Nitrogen, and Carbon Dioxide
(The American Institute of Physics, 1957-09)
The mobility constants for oxygen negative ions in He, Ne, A, Kr, Xe, H2, N2, and CO2, each containing various partial pressures of O2 were measured, and extrapolations to zero partial pressure of O2 were obtained. A ...
Raman Spectra, Vibrational Assignments, and Force Constants for BH3CO and BD3CO
(The American Institute of Physics, 1957-05)
Raman spectra of BH3CO and BD3CO have been obtained for the liquid state at —80°C, and a complete assignment of the sixteen fundamentals of the two molecules has been made with the help of the Teller‐Redlich product rule ...
