Phys. Rev. Lett. 85, 4856–4859 (2000)Measurement of Direct Photon Emission in K+→π+π0γ DecayReceived 13 July 2000; published in the issue dated 4 December 2000 We have performed a measurement of the K+→π+π0γ decay and have observed 2×104 events. The best fit to the decay spectrum gives a branching ratio for direct photon emission of (4.7±0.8±0.3)×10-6 in the π+ kinetic energy region of 55 to 90 MeV and requires no component due to interference with inner bremsstrahlung. © 2000 The American Physical Society URL:
