Beta particles are actually electrons (-e) or can be  positrons.The mass of one electron or beta particle is  9.1095*10-31 kilograms or  0.000548597 AMU which is about 1/20 â¦ 00 times the mass of a  proton or neutron.eta particles are actually electrons (-e) or can be  positrons.The mass of one electron or beta particle is  9.1095*10-31 kilograms or  0.000548597 AMU which is about 1/20 â¦ 00 times the mass of a  proton or neutron.
Hot Dark Matter. This elusive particle was predicted to exist as early as 1931 by physicist Wolfgang Pauli in order to account for the conservation of momentum and energy in beta decay. Beta decay is a process whereby a free neutron, after roughly 12 minutes, decays into an electron, proton, and an electron anti-neutrino.
