Energy Mismatch and Cutoff Waves in a Two‐Dimensional Space‐Charge Flow
(The American Institute of Physics, 1962-01)
A general treatment of the input boundary value problem for two‐dimensional space‐charge flow is developed using a theory of electrostatics (Thomson's) which notes that in an electrostatic problem the electric field ...
Asymmetric rotator model of odd-mass nuclei
(Elsevier, 1962)
The asymmetric rotator model of Dadydov and Filippov has been extended to odd-mass nuclei by coupling a single nucleon to an inert core of well stabilized asymmetric equilibrium shape. Rotational energies are calculated ...
Further Studies of Cr 1 Emission from the Shock Tube
(The American Institute of Physics, 1962-12)
Simulation of Condensed‐Explosive Detonation Phenomena with Gases
(The American Institute of Physics, 1962-02)
The detonation of a condensed explosive within a solid container and the detonation of a gaseous explosive within an inert‐gas boundary are found to be hydrodynamically similar situations. Experiments with hydrogen, methane, ...
Heat Capacities and Thermodynamic Properties of Two Tetramethylammonium Halides
(The American Institute of Physics, 1962-05-01)
Heat capacities of tetramethylammonium chloride and bromide were determined by low‐temperature adiabatic calorimetry from 5° to 350°K. Derived thermodynamic properties were then calculated. Two transitions were found in ...
Inversion-vibration and inversion-rotation interactions in the ammonia molecule
(Elsevier, 1962)
An attempt has been made to extend the theory of ammonia inversion in order to account for the dependence of the inversion splitting on the full set of vibrational and rotational quantum numbers. The potential energy of ...
Leading Edge of a Shock‐Induced Boundary Layer
(The American Institute of Physics, 1962-10)
The boundary layer which is formed as a shock wave propagates down a shock tube causes both shock attenuation and shock curvature. Hartunian studied the curvature effect; however, as he points out, because of the singularities ...
Second Virial Coefficient for the Spherical Shell Potential
(The American Institute of Physics, 1962-02-15)
Values of the second virial coefficient for the three‐parameter spherical shell potential are tabulated over wide ranges of temperature and shell size. The potential, which is not new, results from the interaction of two ...
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)
Thermal Properties Based upon Heat Capacity and Decomposition Pressure of Tetramethylammonium Hydrogen Dichloride. Nature of the Hydrogen Bond in the [Cl☒H☒Cl]— Ion
(The American Institute of Physics, 1962-05-15)
The heat capacity of tetramethylammonium hydrogen dichloride was determined from 5° to 350°K by adiabatic calorimetry and the derived thermodynamic properties were calculated. No thermal anomalies were found. Molal values ...
