摘要：

We present a study of the radiative decay in the K+K-K+K- and K+K-KS0KL0 final states. A pseudoscalar state is observed in the invariant-mass spectrum at 2.22 GeV/c2 with a width of 150 MeV/c2. The product branching ratios are BB10-4 for the K+K-K+K- mode and B0.6)×10-4 for the K+K-KS0KL0 mode. No evidence for 2++ states below 2.4 GeV/c2 is found in this radiative decay mode. © 1990 The American Physical Society.
