Vector-like fermion and standard Higgs production at hadron colliders
(Elsevier, 1990-04-09)
Vector-like fermions are characterized by large neutral current decay rates, in particular into Higgs bosons. If they exist, their clear signals at hadron colliders open a window to Higgs detection, especially to the ...
Schlieren measurements of the hydrodynamics of excimer laser ablation of polymers in atmospheric pressure gas
(The American Institute of Physics, 1990-08-01)
Pulsed schlieren photography and fast helium‐neon laser deflection are used to study the hydrodynamics of laser ablation of polyethyleneterephthalate and polymethylmethacrylate by pulsed KrF (248 nm) radiation in atmospheric ...
Chlorite control of correlations between strain and anisotropy of magnetic susceptibility
(Elsevier, 1990)
Anisotropy of magnetic susceptibility (AMS) has in the past been used as an indicator of finite strain; mathematical relationships between the measured AMS ellipsoid and the finite strain ellipsoid in slates are numerous. ...
Kinetics and fractal properties of the random sequential adsorption of line segments
(IOP Publishing Ltd, 1990-11-07)
The random sequential adsorption (RSA) of infinitely-thin line segments is studied by computer simulation. It is shown that the exponent for the time dependence of the surface coverage increases beyond the value 0.33, ...
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 ...
Computations of three‐dimensional Rayleigh–Taylor instability
(The American Institute of Physics, 1990-05)
The fully three‐dimensional deformation of an interface between two fluids resulting from a Rayleigh–Taylor instability is studied numerically in the limit of weak stratification. The Navier–Stokes equations are solved by ...
Structure of 11Li in the cluster-orbital shell model for the 9Li+n +n system
(Elsevier, 1990-04)
The properties of 11Li are studied in detail in the cluster-orbital shell model assuming the structure of 9Li+n+n. The interactions acting between the constituent particles are carefully determined consistently with available ...
Spin fluids in van Stockum cylinders
(IOP Publishing Ltd, 1990-03-01)
Within general relativity, the stress-energy content of van Stockum's two-dimensional dust interior is extended to include a two-dimensional spin fluid. The metric and spin-fluid parameters are expressed in terms of one ...
Elongational viscosity by fiber spinning
(Steinkopff-Verlag; Steinkopff ; Springer Science+Business Media, 1990-09)
Isothermal melt, fiber-spinning was recently analyzed by means of a nonlinear, integral, constitutive equation that incorporates shear history effects, spectrum of relaxation times, shear-thinning, and extension thinning ...
