Comparison of Exp‐6, L.‐J.(12,6), and Sutherland Potential Functions Applied to the Calculation of Differential Scattering Cross Sections
(The American Institute of Physics, 1959-11)
On the Notion of Pressure in a Canonical Ensemble
(The American Institute of Physics, 1950-08)
Recently a controversy has arisen between J. De Boer and H. S. Green concerning the notion of pressure in a canonical ensemble. According to Green, only classically is the pressure as derived from the partition function ...
Equipartition of Energy and Local Isotropy in Turbulent Flows
(The American Institute of Physics, 1957-10)
Homogeneous turbulence in which 〈v2〉 = 〈w2〉 ≠ 〈u2〉 was produced experimentally, where 〈u2〉, 〈v2〉, and 〈w2〉 are the mean‐square turbulent velocities in x, y, and z direction, respectively. The decay of turbulence and the ...
[beta]-ray spectroscopy using a hollow plastic scintillator
(Elsevier, 1958-08)
Specially designed plastic scintillators employing a hollow construction to minimize electron scattering have been used to study accurately [beta]-spectral distributions down to energies of less than 0[middle dot]1 MeV. ...
Energy Levels and Thermodynamic Properties of the Internal Rotator
(The American Institute of Physics, 1950-04)
To facilitate the calculation of the thermodynamic properties of internal rotators lying outside the limits of available tabulations, methods of determining the energy levels are studied for the purpose of finding the most ...
Electronic Spectra of Polyacetylenes
(The American Institute of Physics, 1956-10)
The low‐temperature emission spectra in rigid glass solutions of several substituted polyacetyelnes have been investigated. All the compounds phosphoresced with decay lifetimes ranging from 0.01 to 0.3 second. None of the ...
Exact Current‐Voltage Relation for the Metal‐Insulator‐Metal Junction with a Simple Model for Trapping of Charge Carriers
(The American Institute of Physics, 1957-04)
The exact solution to the diffusion equation for one kind of charge carrier is obtained for the metal‐insulator‐metal junction where trapping of the charge carriers may occur in the body of the insulator. The effect of ...
Propagation of Waves in Helical Wave Guides
(The American Institute of Physics, 1958-01)
The field configuration near the conductors of a helical wave guide is obtained from the solution of the spatial‐wave equation for a developed helix. This solution is first obtained for the case of tape conductors and then ...
Angular Distributions in the 10B(d,p)11B Reaction
(IOP Publishing Ltd, 1954-08-01)
Angular distributions of six proton groups from the reaction 10B(d,p)11B were obtained using a scintillation counter spectrometer and an incident deuteron energy of 7.7 MeV. Distributions for the three longest range groups ...
Frequency Shift of the CO Stretching Band in Polypeptides and Proteins
(The American Institute of Physics, 1955-07)
