The primary argument against the neutrino being a kind of photon, and of Rutherford's hypothesis that the neutron is a proton and electron, is spin. For example, the nucleus of nitrogen consists of 7 protons and 7 neutrons and has an experimentally observed spin of 1. Yet if it is assumed the neutrons contain electrons, the total number of 1/2 spin particles is odd (3x7) and thus the spin of nitrogen should be half integer.
