Abstract :
We present the results of the observations performed in the occasion of the 21st June 2001 total solar eclipse, looking for visible photons emitted through a possible radiative decay of solar neutrinos. We establish lower limits for the ν2 or ν3 proper lifetimes τ0/m⩾103 s/eV, for neutrino masses larger than 10−2 eV.
