We present a study of the interaction of low energy electron neutrinos
on nuclei that undergo beta decay. Remarkably, we found that in
the limit of very low neutrino energy the product of the cross section times
the neutrino velocity take values up to $10^{-42}$ cm$^2$ $c$ for some specific
nuclei that decay via allowed transitions. The absence of an energy threshold
and the value of the cross section single out these processes as the only ones
having a realistic chance to unambiguously detect electron neutrino with small
energy and mass. This represents a realistic though very demanding approach
for future experiments aimed at a direct detection of the cosmological relic
neutrino background.
