This research is the theoretical investigation of the β-decay spectrum of free neutron decay using Fermi‘s Golden rule. In the β-decay spectrum with respect to the kinetic energies of the beta particle, end point energy gives the upper limit or maximum energy of β-particle. The maximum beta particle energy, max E (or) Q of free neutron decay is 0.782 MeV. According to the calculation, the maximum probability of beta decay is observed for beta particle energy of 0.261 MeV (i.e., one third of the end point energy). The average kinetic energy of β-particle is 0.302 MeV which is nearly equal to the one third of maximum energy of emitted beta particle. In this research, two cases of neutrino mass, zero neutrino mass and finite neutrino mass, are also observed for beta decay.
