Neutrinos and Gamma rays [OR: Gamma rays and Neutrinos]

We know an atomic Nucleus [Z≥2] be formed by some Protons combining together with some π-Mesons [1], and a π-Meson build up by an Electron and a Neutrino [2], that is A π-Meson (π) = an Electron (E) + a Neutrino (Ne) and A Neutron (N) = a Proton (P) + an Electron (E) + a Neutrino (Ne) In a radioactive decay of an atomic nucleus, we know, which includes the emission of Alpha particles, Beta particles, and Gamma rays, and there be A α = 2P+2N = 2P+2P+2π = 4P+2E+2Ne A β = a E Then, what is the resource of Gamma rays? There is no doubt; the neutrino beams is Gamma rays; or say Gamma ray is the neutrino beam! That is too sayin
