High-Energy Multiparticle Reactions
Hadronic multiparticle reactions at very high energies are reviewed with emphasis on current theoretical pictures and models. © 1972 The American Physical Society.
Scaling Relation for a Quantity Related to Particle Production Multiplicities
A scaling relation, dln[σn(s)]dlns→p(nlns), for high-energy production of n particles is proposed. This relation is supposed to be valid for large n and large s. An extension to present energies is suggested and compared with experiment. © 1973 The American Physical Society.
An Approach toward Energy Balance Simulation over Rugged Terrain
We develop a digital computer model, based upon equilibrium temperature theory, of the magnitudes of the components of the energy balance for a mountainous topographic surface. The model includes an algorithm for calculating slope, exposure, and horizon information for every point on a digitized grid. Incoming solar and thermal radiation are then s...
Telecommunications/ transportation substitution and energy conservation Part 1
The substitution of telecommunications for transportation is held to have major potential for increasing energy conservation within the USA, other developed nations, and even developing nations. This article is the first of a two-part re-examination of the substitution hypothesis based on research and experience of the past decade. This part examin...
Measurement of Energy Correlations in e+e-→Hadrons
...
Energy correlations have been measured with the MARK II detector at the PEP storage ring (Stanford Linear Accelerator Center) at c.m. energy of 29 GeV and are compared to first-order QCD predictions. Fragmentation processes are significant and limit the precision with which the first-order strong-coupling constant can be determined. © 1982 The Amer...
Distance Dependence of Electronic Energy Transfer to Semiconductor Surfaces: n3π* Pyrazine/GaAs(110)
Energy transfer from n3* pyrazine to GaAs(110) has been studied. Within experimental error, a classical dielectric model quantitatively reproduces measurements of the distance-dependent lifetime for emitter-surface separations from 430 to 20. Analysis of the energy transfer shows that the molecular electronic excitation is dissipated through the cr...
Binary progenitors of Supernovae
Supernovae of both Type I (hydrogen-poor) and Type II (hydrogen-rich) can be expected to occur among binary stars. Among massive stars (>10 M•), the companion makes it more difficult for the primary to develop an unstable core of >1.4.M• while still retaining the extended, hydrogen-rich envelope needed to make a typical Type II light curve. Among 1...
Energy spectra from “beam-target” nuclear reactions in magnetic fusion devices
Analytical expressions for the energy distribution of fusion products created in "beam-target" fusion reactions in a strong magnetic field are derived. © 1985.
Mass and energy transfer to seabirds in the southeastern Bering Sea
It has been hypothesized that differentiation in food web structure occurs across the Bering Sea continental shelf as a result of seasonal differentiation of water masses. We tested this idea using an apex predator, pelagic birds. Seasonal abundance of birds in central Bristol Bay was estimated from counts made while underway between hydrographic s...
Quasars at 25
In the quarter century since the first optical identification of a "radio star" (3C 48), astronomers have come to general agreement that the underlying quasar energy source is accretion onto a massive black hole. There is much less agreement on the detailed physics of the processes by which this energy is converted to the forms observed, but this h...
