Design of an enhanced 1 GeV electron neutrino beam
(Elsevier, 1985-05-15)
An enhanced [nu]e beam would be useful for experiments that have been proposed to investigate the time evolution of a [nu]e beam or to test the universality of [nu]e and [nu][mu] interactions. We have performed detailed ...
One-dimensional luminescence kinetics; a submicron probe
(Elsevier, 1988-02)
Cylindrical naphthalene wires (10-1200 nanometer diameter) exhibit one-dimensional exciton annihilation kinetics for 10-30 nm wires, three-dimensional behavior for 100-1200 nm wires and a crossover diameter increasing from ...
Decoupling in theories with anomalies
(Elsevier, 1981-11-02)
We consider the appearance of infinities due to the triangle anomaly in the Weinberg model by introducing terms in the lagrangian which restore the Ward identities. It is then shown that these are not the same as the ...
Fractal-like energy transport and fusion in a naphthalene-doped polymeric glass
(Elsevier, 1984-12)
Singlet energy transport in naphthalene-doped poly (methylmethacrylate) (PMMA) samples has been found, by doping with anthracene, to follow Stern-Volmer kinetics with a transfer rate constant ca. 2x109. Delayed fluorescence ...
Gammatrica
(Elsevier, 1989-06-12)
Equations for strings and traces of strings of [gamma] matrices are summarized.
Measurement of 90Sr in reactor wastes by Cerenkov counting of 90Y
(Elsevier, 1987)
Determination of 90Sr in low-level radioactive wastes (LLW) from reactors is difficult because of the presence of so many other radionuclides in samples of interest. This problem was dealt with by radiochemical separation ...
Neutrinos from SN1987a in the IMB detector
(Elsevier, 1988-02-01)
A burst of eight neutrino events preceding the optical detection of the supernova in the Large Magellanic Cloud has been observed by the IMB detector. The events span an interval of 6 s and have visible energies in the ...
The mercedes-benz approach to [gamma]-ray astronomy
(Elsevier, 1988-02-01)
The sensitivity requirements for ground-based [gamma]-ray astronomy are reviewed in the light of the most reliable estimates of stellar fluxes above 100 GeV. Current data strongly favor the construction of detectors with ...
A waveshifter light collector for a water Cherenkov detector
(Elsevier, 1987-11-15)
A device has been developed which is capable of doubling the light collection capability of a 5 inch hemispherical photomultiplier tube. Known as a "waveshifter plate", its geometry is adaptable to various applications. ...
Softly broken supersymmetry and SU(5)
(Elsevier, 1981-12-21)
We construct an explicit realistic SU(5) model in which softly broken supersymmetry is used to protect the Higgs doublets from quadratic mass renormalization. The model requires one natural but incredibly accurate adjustment ...
