Recent BES Results on Hadron Spectroscopy

Abstract

We present recent results from the BES experiment on the observation of the Y(2175) in J/ψ\to ϕf_0(980) η, study of η(2225) in J/ψ\to γϕϕ, and the production of X(1440) recoiling against an ωor a ϕin J/ψhadronic decays. The observation of ψ(2S) radiative decays is also presented.
