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 ...
Radiation-affected laminar flame propagation
(Elsevier, 1982)
Increased laminar flame thickness and flame speed under the influence of radiation is shown in terms of an original heat transfer number where is the weighted nongreyness, [kappa]p and [kappa]R are the Planck mean and ...
Large scale surface structure formed during GaAs (001) homoepitaxy
(The American Institute of Physics, 1994-02-14)
Atomic force microscopy studies have been performed on GaAs (001) homoepitaxy films grown by molecular beam epitaxy. Multilayered features are seen to evolve when the growth conditions favor island nucleation. As the ...
Linear and nonlinear computations of the 1992 Nicaragua earthquake tsunami
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1995-09)
Numerical computations of tsunamis are made for the 1992 Nicaragua earthquake using different governing equations, bottom frictional values and bathymetry data. The results are compared with each other as well as with the ...
Universality in the Thomas-Fermi-von Weizsäcker model of atoms and molecules
(Springer-Verlag, 1990-05)
We study the Thomas-Fermi-von Weizsäcker theory of atoms and molecules. The main result is to prove universality of the structure of very large atoms and molecules, i.e., proving that the structure converges as the nuclear ...
A mass zero cluster expansion. Part 1: The Expansion
(Springer-Verlag, 1981-09)
A cluster expansion is developed and applied to study the perturbation λ(Δφ) 4 of the massless lattice field φ in dimension 3. The method is loosely inspired by the work of Gawedzki and Kupiainen on block spin techniques ...
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 ...
Dynamics of excimer laser‐ablated aluminum neutral atom plume measured by dye laser resonance absorption photography
(The American Institute of Physics, 1991-04-15)
We report the first dye laser resonance absorption photographs of a single species of aluminum ground‐state neutral atoms in the plume ablated from solid aluminum by KrF excimer laser radiation. Aluminum ground‐state neutral ...
