Abstract
Recent results of the BESIII experiment in spectroscopy of spin-singlet charmonium are presented. Properties of hc, ηc and ηcâ² states are measured using the largest data sample of 106M of Ïâ² decays. The masses, widths, and production rates of these states are reported. The transitions between charmonium state Ïâ² â γγJ/Ï and the measurement of multipole amplitude in Ïâ²âγÏc2 are presented. The branching fractions for ηcâ²,ÏcJ decays to vector meson pairs and the radiative decay ÏcJâγγ are reported. Some preliminary results of charm meson decays are presented.
