On isotropic invariance of CP-noninvariant electromagnetic vertices
The isotopic selection rules are discussed in the framework of a scheme of strong CP-violation proposed by Lee. (According to these scheme the charge conjugation operators Cst and Cγ leaving invariant strong and electromagnetic interactions, respectively, do not coincide with each other.) It is shown that in this scheme CP-noninvariant vertices describing the emission of photons by ordinary hadrons must be necessarily isotopically invariant (ΔI = 0) independent of whether the principle of minimal electromagnetic interaction is applicable to so called a-particles and whether these particles are isottopic singlets.
