Neutrinos and Gamma Rays
Neutrinos and Gamma Rays
Neutrinos and Gamma Rays Emission of a beta particle produces an energy change in the nucleus of an atom. The energy change that is observed, however, does not add up to satisfy the Law of Conservation of energy. The conservation law can be balanced if another particle, called the neutrino is part of this process. In the time it takes to read just this sentence, more than a billion of them will have passed unnoticed through the reader\'s body. Neutrinos may account for an appreciable portion of
