N2 - We extract the G-parity-violating branching ratio (Formula presented) from the effective (Formula presented)-(Formula presented) mixing matrix element (Formula presented) determined from (Formula presented) data. The (Formula presented) partial width can be determined either from the timelike pion form factor or through the constraint that the mixed physical propagator (Formula presented) possesses no poles. The two procedures are inequivalent in practice, and we show why the first is preferred, to find finally (Formula presented).
