Study of Scalar Mesons at BES-II

Recent results from the BES-II experiment on hadron spectroscopy using J/ψ and ψ′ data samples collected in e+e− annihilation are presented, including a study of the scalar particles in J/ψ radiative and hadronic decays, the observation of X(1810) in J/ψ→γϕω, as well as pair production of scalars in χc0 hadronic decays.
