Design for improved resolution in a time‐of‐flight mass spectrometer using a supersonic beam and laser ionization source
(The American Institute of Physics, 1985-03)
This article describes the design of a time‐of‐flight mass spectrometer (TOFMS) constructed for optimum use with resonance‐enhanced multiphoton ionization spectroscopy in supersonic beams. The use of the supersonic beam ...
Comparison of light quark and charm quark fragmentation
(Elsevier, 1985-10-31)
Separate samples of charm quark and light quark (u, d, s) jets have been isolated in an experiment studying e+e- annihilations at . The results come from data corresponding to an integrated luminosity of 111 pb-1 collected ...
Complex coordinate methods for hydrodynamic instabilities and Sturm-Liouville eigenproblems with an interior singularity
(Elsevier, 1985-02)
Calculations of inviscid, linearized waves in fluids are very difficult when a mean wind or current U(y) is included because the differential equation is singular wherever U(y)=c, the phase speed. These "critical latitude," ...
Experimental limits on monojet production in e+e- annihilation at 29 GeV
(Elsevier, 1985-06-20)
A search was made for e+e--->X1X2 where X1 consists of one or more light unobservable particles and X2 decays promptly to a visible jet of particles. One event was found for an integrated luminosity of 176 pb-1, a rate ...
On the validity of Smoluchowski’s equation for cluster–cluster aggregation kinetics
(The American Institute of Physics, 1985-06-01)
Large‐scale computer simulations of cluster–cluster aggregation of particles undergoing Brownian motion have been performed to investigate the kinetic properties of the coagulation process. It is shown that the mean‐field ...
