Large-aperture low-dispersion exposures obtained with the IUE short-wavelength camera have been reanalyzed to examine the possibility of using nonstandard electroweak models to explain the steplike signal of 5-sigma significance in the cosmic background claimed by Auriemma et al. (1985). The present results show that no evidence yet exists for the postulated cosmic UV radiation from neutrino decay. Error bars of the order of 20,000 photons/sq cm per s per A per sr are found for the brightnesses… Expand

Physics of Neutrinos
Ever since it was first proposed the neutrino has played a crucial role in the advancement of our understanding of particle physics. The neutrino was first conjectured by W. Pauli in a letter writtenExpand
The spin polarized photoemission from non-magnetic metals
Since 1969 (1) it was well known that photoelectrons emitted from non-magnetic targets after excitation by circularly polarized radiation might be polarized.Such a theoretical prediction has itsExpand
Relativistic Effects in Photoemission from Alloys
A relativistic theory of photoemission is applied to calculate angle-, energy- and “spin”resolved photoemission spectra from the (1,0,0) surface of Cu3Au, both in the ordered and solid solutionExpand
