Abstract
We present the results of the measurements performed in the occasion of the 2001 total solar eclipse, looking for visible photons emitted through a possible radiative decay of solar neutrinos. We establish lower limits for the ν_2 and ν_3 proper lifetimes above 10^3 s/eV, for neutrino masses larger than 10^{-2} eV.
