Theory of Oscillation of a Viscoelastic Medium between Parallel Planes
(The American Institute of Physics, 1959-12)
A theoretical description of sinusoidal oscillation of an incompressible viscoelastic medium between fixed infinite parallel planes is presented. The mechanical properties of the viscoelastic medium under sinusoidal shear ...
Conjugation and Polar Effects in Butadiene
(The American Institute of Physics, 1959-04)
Various valence bond structure functions are projected onto approximate ground‐state wave functions of butadiene. The most important structure, C☒C☒C☒C, contributes approximately 70% of the total. The next most important ...
Ruby as a Maser Material
(The American Institute of Physics, 1959-07)
The reasons for the initial choice of ruby as a maser material are outlined and some measurements of the parameters in the spin Hamiltonian and of spin relaxation times are reported. The relative merits of single‐ and ...
Transport theory
(Elsevier, 1959-01)
The usual theories of electrical conductivity suffer from a number of weaknesses. A more general theory will be described which gives the entire density matrix of a system of charge carriers in the steady state. It will ...
Bending Motions in the Dihalides of Group II Metals
(The American Institute of Physics, 1959-01)
A polarizable ion model is used to calculate the force constants for bending in the dihalides of the secondgroup metals. The results indicate that the bending constant is a sensitive function of the polarizability of the ...
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)
High energy, high current synchrotron injector
(IOP Publishing Ltd, 1959-07-01)
The construction and testing of a pulsed 450 keV injector for an electron synchrotron are described. High voltage is obtained with a spark gap and pulse transformer. The electron-optical system consists of a series of ...
Inhibition of Hydrodynamic Instability by an Electric Current
(The American Institute of Physics, 1959-03)
The inhibition of instability of a viscous fluid contained in a circular cylinder and heated from below by an electric current is investigated. Previous results indicate that, for a thermally nonconducting wall, the critical ...
