Subcores in cosmic-ray air showers and high transverse momentum
(IOP Publishing Ltd, 1981-09-01)
The rate of subcores in cosmic-ray air showers has been measured near sea level with a close-packed 35 m2 array of spark chambers. A large transition effect was observed from wood beams in the original roof. After the first ...
Electron diffraction studies of laser‐pumped molecules. II. Collisionally assisted absorption by SF6
(The American Institute of Physics, 1981-09-15)
Supersonic microjets of SF6 were pumped with the cw output of a CO2 laser. Power densities ranged from 2–4 kW/cm2 at the nozzle exit (P?200 Torr) to 25 kW/cm2 downstream. Amplitudes of molecular vibration were found to ...
Looking for oscillations
(Elsevier, 1981-10-08)
A search is performed for the antineutrino oscillation process with 15' bubble chamber data. Assuming maximal mixing, we obtain for the neutrino mass difference parameter [Delta] 2 (90% c.1.). Alternatively, for [Delta] ...
An image deblurring method using diffraction gratings
(Elsevier, 1981-01-15)
A method of image deblurring is described, in which the restoration filter is derived from Ronchi rulings. Although two-dimensional spatial filtering is used, the method employs a line source, resulting in significant noise ...
On the nature of the Gardner transformation
(The American Institute of Physics, 1981-03)
It is shown that every higher Korteveg‐de Vries equation can be included in a one‐parameter family of integrable equations.
Limits on the production of neutral penetrating states in a beam dump
(Elsevier, 1981-06-11)
We present limits on the production of neutral penetrating states produced in 28 GeV proton nucleus collisions. We obtain limits for light, heavy and unstable neutral states. For light stable states our limit [sigma]I[si ...
Testing technicolor theories
(The American Institute of Physics, 1981-02)
We provide improved estimates of the masses, decay modes and widths, and production cross sections of the physical particles expected in theories with dynamical symmetry breaking. The most important results are charged ...
Errors in the numerical integration of a linearized equation for particle flows
(Elsevier, 1981-10)
Optical Holography with Partially Coherent Radiation
(The American Institute of Physics, 1981-10)
Holograms can be formed in light of little or no temporal coherence. The coherence requirements for Gabor in‐line holography are examined. It is shown that, with achromatic interferometers formed from diffraction gratings, ...
On the Killing surface—event horizon relation
(The American Institute of Physics, 1981-04)
A projective transformation on the scalar norm and twist of a timelike killing vector can be used to generate new space‐times. The effect of the transformation on the new Killing surface and its relation to the lcoal event ...
