Capturing Relic Neutrinos with beta-decaying nuclei
We summarize a novel approach which has been recently proposed for direct
detection of low energy neutrino backgrounds such as the cosmological relic
neutrinos, exploiting neutrino/antineutrino capture on nuclei that
spontaneously undergo beta decay.Comment: Talk given by G. Mangano at TAUP2007 Conference, Sendai, Japan,

Probing Low Energy Neutrino Backgrounds with Neutrino Capture on Beta Decaying Nuclei
We study the interaction of low energy neutrinos on nuclei that spontaneously
undergo beta decay showing that the product of the cross section times neutrino
velocity takes values as high as 10^{-42} cm^2 c for some specific nuclei that
decay via allowed transitions. The absence of energy threshold and the value of
the cross section single out these processes as a promising though very
demanding approach for future experiments aimed at a direct detection of low
energy neutrino backgrounds such as the cosmological relic neutrinos.Comment: Includes a discussion of local relic neutrino density effect on
neutrino capture rate. Accepted for publication in JCA
