Peaslee has considered the interesting possibility that the principle of charge independence, now believed to hold for nucleons and pions, may extend to the new unstable particles as well. In order to discuss this suggestion, let us suppose that both "ordinary particles" (nucleons and pions) and "new unstable particles" (Vq, V4, τ, etc.) have interactions of three kinds: (i) Interactions that rigorously conserve isotopic spin. (We assume these to be strong.) (ii) Electromagnetic interactions. (Let us include mass-difference effects in this category.) (iii) Other charge-dependent interactions, which we take to be very weak.
