摘要：
We present the measurement of the mass and width of the eta(e)(2S) meson in the gamma gamma -> K degrees K-s(+/-)pi(+/-)process, and eta(c)(2S) first observation in the gamma gamma -> K+K- pi(+)pi(-)pi(degrees) process. The chi(e2) (2P) resonance is searched, but no significant signal is found.
