• It is shown that the special mass reversal MR(1)and MR(2)can be applied to both the weak Fermi type interaction and the weak Yukawa type interaction without any internal contradiction in the theory of MR(4)and MR(3)(for strong interactions). The selection rules obtained are consistent with experiment and suggest taking the universal Fermi interactions with V-A coupling as the primary interactions for all the lepton processes. The mass reversibility of the theory under MR(1)requires that the space parity is not conserved in all the weak interactions and that the mass of the neutrino must be exactly zero. MR(2)invariance allows only a linear combination of(AV)couplings when the coupling is independent of the explicit masses. It is assumed that leptons are conserved and are C or D type fields under mass reversal, guaranteeing the conservation of baryons automatically. From the requirement of MR(4)and the consistency of the theory, the neutrino is shown to be a mass parity doublet. It is shown from the application of mass reversal to the lowest order diagrams in g that the unwanted lepton processes are forbidden or explained even when the μ^-, e^- and ν are taken as the particles. The prediction of the rarity of π→e+ν, π→e+ν+γ and Κ→e+ν is given by extending the universal interaction proposed by Huang and Low in such a way that it is invariant under mass reversal. If this is true, the neutrino must have four components in a strict sense, and in the usual experiments it is observed as if it were a two component field. If MR(3)is assumed to be applied even to Fermi interactions, MR(3)requires uniquely that the universal interactions have V-A coupling, and the helicity of the neutrino is -1. The decays Κ→(π)+ν+ν' are shown to be ruled out by the mass parity conjugation invariance and MR(1), provided the leptons are C or D type fields under mass reversal. The mass parity is shown to be related closely to the strangeness which is the important difference between our theory and Sakurai's one.
