Abstract

We confirm the observation of a spin-1 resonance at 1423 MeV in the KS0K± system produced in single-tagged two-photon interactions. The Dalitz plot indicates that this resonance decays primarily via a K*K intermediate state. We measure a radiative width times branching ratio BKK»(M2/Q2)*=3.2±1.4±0.6 keV on the assumption of a -pole form factor. © 1987 The American Physical Society.
