Virialization in N-Body Models of the Expanding Universe: 1. Isolated Pairs
(Univ Chicago Press, 1985)
A unified theory of aerosol coagulation
(IOP Publishing Ltd, 1988-06-14)
A unified theory of the coagulation of aerosols is presented based upon the solution of a generalised diffusion equation which describes classical diffusion due to Brownian and turbulent motion as well as the effect of an ...
Bound states of vector bosons
(Elsevier, 1984-05-17)
The anomalous CERN events are interpreted as a new state decaying into a photon and a lepton pair. It is speculated that this new state might be a composite state involving vector bosons.
An optically detected magnetic resonance study of Mn4+ in Cs2GeF6 and K2GeF6
(Elsevier, 1988-11-15)
The photoexcitation and photoluminescence spectra (2E 4A2) of MnF62- diluted in Cs2GeF6 and K2GeF6 host lattices have been recorded at liquid helium temperature. The manganese coordination geometry is Oh in Cs2GeF6 and ...
REVIEW ARTICLE: The relationship of the D-X centre in AlxGa1-xAs and other III-V alloys with the conduction band structure
(IOP Publishing Ltd, 1988-12-01)
The electrical properties of the AlxGa1-xAs alloys for x>or=0.24 are dominated by deep donors which appear in undoped and doped crystals. The corresponding defects, which are now more commonly known as D-X centres, also ...
Combutational studies of end-wall flame quenching at low pressure: The effects of heterogeneous radical recombination and crevices
(Elsevier, 1983-01)
A computational study of the effect of heterogeneous radical destruction and crevices on end-wall flame quenching in a lean CH4---O2---Ar mixture at low pressure has been performed. The unsteady conservation equations for ...
Electron diffraction studies of hot molecules. I. Observed and calculated thermal expansions of SF6, CF4, and SiF4
(The American Institute of Physics, 1982-08-15)
A new method is described for the rapid heating (10−5–10−6 s) of gas molecules for study by electron diffraction. Laser irradiation of the tip of a micronozzle makes it possible to determine structures, amplitudes of ...
Computational approach to steady-state eutectic growth
(Elsevier, 1989-04)
We formulate a boundary integral approach to the determination of periodic steady-state eutectic growth patterns. The numerical implementation of this method allows us to compute the band of allowed velocities for a given ...
Low‐loss optical waveguides made with molecular beam epitaxial In0.012Ga0.988As and In0.2Ga0.8As‐GaAs superlattices
(The American Institute of Physics, 1986-06-02)
We demonstrate for the first time low‐loss optical guiding in In‐doped GaAs. Ridge waveguides are made with single In0.012Ga0.988As ternary layers and In0.2Ga0.8As‐GaAs superlattices. Attenuation constants of ∼1.3 dB/cm ...
An analysis of carrier-mediated photodiffusion membranes
(Elsevier, 1983-08)
Reversible photochromic reactions can be combined with carrier-mediated transport in partially illuminated membranes to achieve very high degrees of flux enhancement. Transport across these membranes can be achieved even ...
