| Abstract | Using 14x10(6) psi(2S) events accumulated at the BESII detector, we report first measurements of branching fractions or upper limits for psi(2S) decays into gamma p (p) over bar, gamma 2(pi(+)pi(-)), gamma(KSK+)-K-0 pi(-)+c.c., gamma K+K-pi(+)pi(-), gamma(KK-)-K-*0 pi(+)+c.c., gamma K-*0(K) over bar (*0), gamma pi(+)pi(-)p (p) over bar, gamma 2(K+K-), gamma 3(pi(+)pi(-)), and gamma 2(pi(+)pi(-))K+K- with the invariant mass of hadrons below 2.9 GeV/c(2). We also report branching fractions of psi(2S) decays into 2(pi(+)pi(-))pi(0), omega pi(+)pi(-), omega f(2)(1270), b(1)(+/-)pi(-/+), and pi(0)2(pi(+)pi(-))K+K-. |
