Abstract
Copious production of S* decaying into π+π- is observed in ψ decay. (974 ± 4 -i14 ± 5) MeV, consistent with the parameters extracted from couplede channel; fits to pheripheral π+π- and K+K- production experiments. The inclusive branching ratio for ψ → S* + X is found to be (0.42 ± 0.08)%. © 1981.
