Measurement of sonic velocity in liquid Refrigerant 12
(The American Institute of Physics, 1977-08)
The sonic velocity in subcooled liquid Refrigerant 12 (CCl2F2) was measured at 26.7 °C using an apparatus designed to investigate transients associated with pipe blowdown. The mean value for sonic velocity obtained from ...
S-wave non-leptonic decays and gauge fields
(Elsevier, 1970-11-01)
S-wave non-leptonic decay amplitudes are obtained from a gauge-field model and the results are also interpreted from the point of view of mixing of particle fields. The model gives different effective enhancements for K- ...
Behavior of Gas Bubbles in Viscoelastic Materials in a Creep Process
(The American Institute of Physics, 1972-07)
This paper investigates the dynamic behavior of a spherical bubble situated in viscoelastic (or elasticoviscous) materials in a creep process. Both the diffusion of the dissolved gas in the material and the thermodynamic ...
12C(7Li, t)16O and stellar helium fusion
(Elsevier, 1978-07-31)
The reaction 12C(7Li, t)16O has been studied at E(7Li) = 34 MeV with the LASL tandem accelerator and QDDD magnetic spectrometer. Angular distributions to levels with Ex J[pi] = 1- levels, which are of great importance in ...
On the Asymptotic Stability of Reactors with Arbitrary Feedback
(The American Institute of Physics, 1970-01)
A theorem for the boundedness and asymptotic stability of a point reactor with an arbitrary feedback is stated and proved. The criteria obtained are shown to be essentially the same as those given by Akcasu and Dolfes. The ...
Modification of Stokes' law for a heated sphere in liquid helium II
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1971-07)
It is shown that the counterflow which occurs at low heat inputs in liquid helium below the λ point modifies the wake behind a steadily moving sphere. The result is valid for a low Reynolds number and limits on the range ...
Measurement of the Thermal Conductivity of Argon, Krypton, and Nitrogen in the Range 800–2000°K
(The American Institute of Physics, 1972-09-15)
The thermal conductivities of argon, krypton, and nitrogen were measured at 760 mm Hg in the temperature range 800–2000°K. Two thermal conductivity columns of different outside diameters were used in the experiments to ...
Electron Relaxation and Molecular Vibrations: Triatomic Systems of the First‐Row Elements, the Methyl Radical, and Diazomethane and Ketene
(The American Institute of Physics, 1970-03-15)
The well‐known second‐order perturbation method is used to correlate the bond–bond interaction constants in ground and excited electronic states of triatomic systems of the first‐row elements, and unusual force constants ...
The long time behavior of a finite amplitude shear Alfven wave in a warm plasma
(IOP Publishing Ltd, 1976-10-01)
The long time behavior of a monochromatic, finite amplitude shear Alfven wave is studied by means of the Krylov-Bogoliubov-Mitropolsky perturbation technique. The plasma model is assumed to be described by the linearly ...
Assignments of the n[pi]* singlet states of p-benzoquinone
(Elsevier, 1974-03-30)
The vapor phase fluorescence spectra of p-benzoquinone-h4 and d4 are reported and discussed in relation to the assignment of the low lying singlet states. The low temperature, polarized single crystal electronic absorption ...
