Comparison and Appraisal of Approximation Formulas for Total Elastic Molecular Scattering Cross Sections
(The American Institute of Physics, 1963-05-15)
The Massey—Mohr (MM), Schiff (S), and Landau—Lifshitz (LL) approximations for the total elastic cross section (Q) are intercompared. All can be shown to follow from the same assumption, (i.e., the classical small‐angle ...
Dynamics of a Gas Bubble Moving in an Inviscid Liquid Subjected to a Sudden Pressure Change
(The American Institute of Physics, 1969-03-15)
A gas bubble moves with constant translatory velocity in a quiescent liquid. Its shape deviates from sphericity due to asymmetrical forces exerted upon its surface. Then the liquid pressure undergoes a step change. It is ...
Vortex wheels in superfluid helium
(Elsevier, 1968-06-17)
It is suggested that the continuous reversal of apparent circulation around a vibrating wire in liquid He II is due to the motion of a vortex-line array called a "vortex wheel".
Electromagnetic radiation from a source in a plasma
(Elsevier, 1961-11)
The problem of determining the electromagnetic radiations from a given charge-current distribution situated in a plasma in the presence of a uniform external magnetic field is solved. Explicit expressions for the asymptotic ...
Extrusion Die‐Electrode Combination for Exploding Lithium Wire
(The American Institute of Physics, 1968-06)
Triple Resonance Method for Molecular hfs Spectroscopy: Measurements on 133Cs19F
(The American Institute of Physics, 1967-11-15)
Three sequential oscillatory fields are employed in a molecular beam electric resonance spectrometer in order to observe molecular hfs transitions which do not obey the criteria for observability in the usual beam apparatus. ...
Electroluminescent Panels as Bright Area Light Sources
(The American Institute of Physics, 1965-07)
Relative Quenching Cross Sections in the Reaction of Hg(63P1) Atoms with Isotopic N2O Molecules
(The American Institute of Physics, 1960-08)
The N14/N15 and O16/O18 isotope effects in the Hg(63P1)‐photosensitized decomposition of nitrous oxide have been measured. Observed isotopic fractionation factors, S0 (interpreted in terms of ratios of rate constants for ...
Burgers' Turbulence Models
(The American Institute of Physics, 1969-09)
A detailed investigation of the stability of the solutions and the growth of secondary solutions beyond the critical points is carried out for the Burgers' model equations. It is found that the transitions at some critical ...
