I will therefore consider in more details double beta decay especially in its neutrinoless channel were I was and am particularly involved, weak neutral currents, solar neutrinos, neutrino oscillation, determination of the neutrino mass and one unusual research of mine to which Bruno was particularly interested. 收起
