The level scheme of 134Ba
(Elsevier, 1967-05-16)
The gamma-ray spectrum associated with the beta decay of 134Cs has been studied with curved-crystal and Ge(Li) spectrometers. The data provide energy and intensity measurements of 11 gamma rays. Coincidence spectra were ...
Nuclear resonance fluorescence and Rayleigh scattering from 203Ti
(Elsevier, 1967-09-01)
The lifetime of the 279 keV excited state of 203Tl was determined to be 0.28+/-0.04 nsec by the method of nuclear resonance fluorescence, using the 212 keV beta radiation for compensation of the recoil energy loss. Using ...
The calibration of a Ge(Li) gamma-ray spectrometer for energy and relative intensity measurements
(Elsevier, 1967)
Two aspects of Ge(Li) gamma-ray spectrometry are discussed. The non-linearity of an amplifier-analyzer system was measured using a precision pulser and was checked with gamma-ray standards. The overall accuracy was 2 parts ...
The decay of 147Nd
(Elsevier, 1967-06-05)
Precision energy measurements on 8 gamma rays in the 147Nd-->147Pm decay were made with a 2m curved-crystal spectrometer. Energies of the 6 other gamma rays were determined with a Ge(Li) spectrometer. The relative ...
Wigner Method in Quantum Statistical Mechanics
(The American Institute of Physics, 1967-05)
The Wigner method of transforming quantum‐mechanical operators into their phase‐space analogs is reviewed with applications to scattering theory, as well as to descriptions of the equilibrium and dynamical states of ...
Band strength and line half-width of the 10[middle dot]4 [mu] CO2 band
(Elsevier, 1967)
Experimental absorption data using a 10[middle dot]4 [mu] CO2 laser have been re-analysed. The band intensity of the 10[middle dot]4 [mu] (1000-0001) CO2 band is 0[middle dot]0184 cm-1 (atm cm273[deg]K)-1+/-5% at 300[deg]K ...
Structure of Turbulence in the Boundary Layer near the Wall
(The American Institute of Physics, 1967-09)
Previous measurements of space‐time correlations of turbulent wall pressure and velocity in the boundary layer were extended to include space‐time correlations between the wall pressure and all three velocity components ...
Bremsstrahlung of Slow Electrons in Neutral Gases and Free‐Free Absorption of Microwaves
(The American Institute of Physics, 1967-06)
Bremsstrahlung of nonrelativistic electrons in a neutral gas is investigated including the polarization and exchange effects. The intensity and spectrum of the bremsstrahlung and of the induced dipole radiation are obtained ...
Matrix Elements for Configuration d4 in a Weak Octahedral Field Using Racah Methods
(The American Institute of Physics, 1967-11-15)
Employing Racah algebra, the general formula for calculating the matrix elements of a weak crystalline field for configuration dn has been derived. Applying this formula the matrix elements for d4 (including spin—orbit ...
Magnetic Interactions for the Electronic Configuration d5
(The American Institute of Physics, 1967-04-15)
Applying Horie's method, the matrix elements of spin—other‐orbit interaction for configuration d5 have been calculated. The magnetic interaction energy has also been calculated for Mn++ by means of perturbation theory. It ...
