Description
An analysis of data at the psi(3.7) resonance gives a partial width to electrons GAMMA(e)=2.2+-0.5keV, and limits on total width 200keV<GAMMA<800keV. The decay psi(3.7)→psi(3.1)π+π- is observed with a branching ratio 0.31+-0.04, and psi(3.7)→psi(3.1) + anything has a branching ratio of 0.54+-0.08. The psi resonances appear to have the same G-parity. An enhancement occurs in the total hadronic cross section at a c.m. energy of about 4.1GeV, rising to about 32nb from a level of 18nb adjacent to peak, which is about 300MeV wide. The integrated cross section for the peak is about 5.5nb-GeV, comparable to that for the psi(3.7) and psi(3.1) resonances
