Search for the Neutrino Magnetic Moment in the Non-Equilibrium Reactor Antineutrino Energy Spectrum
We study the time evolution of the typical nuclear reactor antineutrino
energy spectrum during reactor ON period and the decay of the residual
antineutrino spectrum after reactor is stopped. We find that relevant
variations of the soft recoil electron spectra produced via weak and magnetic
scattering process can play a signigicant role in
the current and planned searches for the neutrino magnetic moment at reactors.Comment: 4 pages LaTeX 2.09. 4 PS figures. Resume of seminar talks given at

Electromagnetic properties of neutrinos
A short review on electromagnetic properties of neutrinos is presented. In
spite of many efforts in the theoretical and experimental studies of neutrino
electromagnetic properties, they still remain one of the main puzzles related
to neutrinos.Comment: The talk presented by A.Studenikin at the International Conference on

Cosmic muon flux at shallow depths underground
We consider the cosmic muon background for the installations located at
shallow depths. We suggest a relatively simple formula for the sea-level muon
spectrum, which allows calculate dependencies of the vertical muon intensity
and integral muon flux density on overburden. Muon flux dependency on the
zenith angle at overburden of 10 to 100 meters of standard rock shows that muon
angular distribution practically does not change in this interval. We present
muon angular distributions for three typical apparatus locations in
measurements on the surface and at shallow depths. It is shown that for such
installations the active shielding "umbrella" should overlap a zenith angle of
\theta ~ 80^o to remove the cosmic muon background.Comment: 9 pages, 6 figures, submitted to Phys.Atom.Nuc
