Abstract
We present a new measurement of the branching ratio of the decay (Formula presented) with respect to (Formula presented) and the first study of the photon energy spectrum in this decay. We find (Formula presented) (Formula presented) Our measurement of the spectrum is consistent with inner bremsstrahlung as the only source of photons in (Formula presented).
