Abstract
The radiative decay K++ has been studied by a high-resolution magnetic spectrometer combined with a NaI(Tl) photon detector system. The momentum spectrum of muon from this decay mode was measured in the region 214.5<p<231.5 MeV/c. The observed partial decay rate of the radiative decay in this region agreed with the QED calculation within the error of 3%. The structure-dependent components of the decay were studied and new values of the form factors were obtained as FV+F()MK<0.23, -2.5<(FV-FA)()MK<0.3. By using these bounds the branching ratio was determined as B(,p<231.5 MeV/c)=(5.40.3)×10-3.
