Pion spectrum in decay of Psi'(3.7) to Psi(3.1).
The decay of Psi' --> Psi + pipi is described by a chiral epsilon model. The general features of the observed dipion spectrum are well reproduced. Comparison with the hadronic decay rho' --> rho + pipi indicates that the Psi'Psiepsilon coupling is relatively suppressed by a factor approximately 10(-2).
