摘要Recent results on Charmonium spectrum and decays at Beijing Spectrometers III (BES-III) experiment will be presented. This report includes the following topics: 1, first measurement of the transition rates of psi' -> pi(0)h(c) and h(c) -> gamma eta(c), and improved measurement of the mass and width of the h(c); 2, observations of chi(cJ) -> VV, with VV being phi phi, omega omega and omega phi as well as chi(c1) -> phi phi and omega omega are first observations; 3, improved measurement of the branching fractions of chi(cJ) decay into neutral pseudo-scalar pairs, including chi(c0,2) -> pi(0)pi(0) and chi(c0,2) -> eta eta. All these measurements are based on the world largest ?' data sample collected with the BES-III detector at the Beijing Electron Positron Collider II (BEPC-II).
