Molecular Beam Measurement of the Hyperfine Structure of 85Rb19F
(The American Institute of Physics, 1966-11-15)
Radio‐frequency transitions between the hfs levels of the J=1 rotational state in 85Rb19F have been observed using a molecular beam electric resonance spectrometer. From these spectra we have obtained values for the constant ...
Molecular Beam Measurement of the Hyperfine Structure of 133Cs19F
(The American Institute of Physics, 1967-11-15)
The magnitudes and signs of the hyperfine interaction constants for 133Cs19F in the J = 1, v = 0, 1, 2 states have been measured with a molecular beam electric resonance spectrometer. The results for v = 0 are: eQ1q1 = ...
Free Convection in a Rotating Medium
(The American Institute of Physics, 1968-09)
Numerical techniques have been used to study natural convection in a fluid subjected to axial rotation. Axisymmetrical flows were studied in two different geometries for a variety of rotational speeds. For case I (R1 = ...
Reflection of Strong Blast Waves
(The American Institute of Physics, 1964-08)
The reflection of strong point‐source blast waves is studied using the continuum concept of flow of ideal gases. Methods of obtaining the upper and lower bounds as well as a Taylor series expansion of the position of the ...
Influence of counterions on the helical conformations of charged polypeptide chains
(Wiley Subscription Services, Inc., A Wiley Company, 1969-11)
No Abstract.
Reactions of High‐Energy, Excited I128 Ions with Gaseous Molecules
(The American Institute of Physics, 1962-01-15)
The manner in which molecular additives inhibit the reaction of (n, γ) activated I128 with CH4 was determined in an effort to observe indirectly reactions of I128 with the additives. The data suggest that (1) O2, N2, and ...
Electronic Interaction Integrals for Atoms Calculated with Laguerre Polynomial Radial Wavefunctions
(The American Institute of Physics, 1967-03-01)
Straightforward evaluation of electronic interaction integrals for many‐electron atoms using Laguerre polynomial radial wavefunctions leads to sums of differences of large numbers. An alternate formulation is presented ...
Density in a Simple Model of the Exosphere
(The American Institute of Physics, 1962-09)
The particle density of a simple model of the exosphere is obtained by solving exactly the collisionless Boltzmann equation. The main point of the solution is that it is a discontinuous, multivalued function of the constants ...
Effect of Transport Properties on Supersonic Expansion around a Corner
(The American Institute of Physics, 1967-05)
The compressible flow of a viscous, heat‐conducting gas around a corner is considered; in particular, the viscous corrections in the expansion region are calculated. The solutions are written in terms of asymptotic expansions, ...
