Deskripsi
Status of the VES setup upgrade is shortly reviewed. A number of one-prong multi-photon final states not (or badly) accessible with the VES before, such as the π−3π0, π−ηπ0 in background favorable mode π−4γ and others, becomes promising for the study. An overview of new data set is presented. The preliminary results of PWA of the π−2π0, system show a clear signal of the f0(980) in the π(1800) decay.
