NEW POSSIBLE DETECTION SCHEMES FOR RELIC GALACTIC NEUTRINOS

We discuss the feasibility of the detection of relic neutrinos that ma y be present in the Galactic halo. We analyse their effect an macrosco pic targets, comparing the detection proposals made so far and present ing new experimental schemes. In all cases the acceleration of the tes t masses is bounded by the value of the refractive index of neutrinos N as follows: a approximate to 10(-19)(N - 1)(x) m s(-2), where (N - 1 ) less than or equal to 10(-8) for ail materials and x = 0.5 in the be st case.
