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 ...
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 ...
The quartic isobaric multiplet mass equation
(Elsevier, 1969-05-05)
The quadratic isobaric multiplet mass equation must be replaced by an expression which is quartic in Tz if the electrostatic interaction is treated in second-order perturbation theory. The coefficients of the cubic and ...
Hyperfine Structure of Sodium Iodide
(The American Institute of Physics, 1969-05-01)
A molecular‐beam electric resonance spectrometer has been used to study radio‐frequency transitions between the hyperfine‐structure sublevels of the J = 1J=1 state of 23Na127I. Transitions for the first four vibrational ...
Mixed crystal infrared study of chain folding in crystalline polyethylene
(John Wiley & Sons, Inc., 1969-10)
Infrared spectroscopic studies have been made of mixed crystals of linear polyethylene and perdeuteropolyethylene. On the basis of normal vibration analyses by Tasumi and Krimm it had been shown that the study of crystal ...
Quasielastic Scattering of Thermal Neutrons by CH3OH and CH3SH
(The American Institute of Physics, 1969-12-15)
We report measurements of the line broadening of thermal neutrons quasielastically scattered from room temperature methyl alcohol and methyl mercaptan in the liquid phase. The linewidths for CH3SH are found to be approximately ...
Generalized seniority for favored J [not equal to] 0 pairs in mixed configurations
(Elsevier, 1969-11-03)
By assigning a pseudo-spin and pseudo-orbital angular momentum (b-spin and c-spin) to the single-particle states in a mixed configuration of identical nucleons, it is possible to classify as B = 0 objects both the favored ...
Detection of Metastable Atoms and Molecules with Continuous Channel Electron Multipliers
(The American Institute of Physics, 1969-09)
On the Wigner Supermultiplet Scheme
(The American Institute of Physics, 1969-09)
Calculation of Wigner and Racah coefficients for the group SU(4)⊃[SU(2)×SU(2)]SU(4)⊃[SU(2)×SU(2)] make it possible to perform the spin—isospin sums in the cfp (fractional parentage coefficients) expansion of the matrix ...
