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, ...
On the Structure of Plane Detonation Waves
(The American Institute of Physics, 1960-09)
A steady planar detonation wave, considered to be a shock wave followed by a reaction zone, is studied with both irreversible and reversible first‐order reaction kinetics. A perturbation solution with first‐order transport ...
Zone Leveling and Crystal Growth of Peritectic Compounds
(The American Institute of Physics, 1961-03)
Homogeneous samples of peritectic semiconducting compounds have been prepared for optical and electrical characterization by combining zone leveling concepts with Bridgeman crystal growth techniques. Proper temperature ...
Structure of normal and contracted tail sheaths of T4 bacteriophage
(Elsevier, 1967-07-28)
The structural arrangement of protein subunits in extended and contracted tail sheaths of T4 bacteriophage has been studied by optical diffractometry of electron micrographs. The analysis of such diffraction patterns shows ...
