摘要：

With a forward tagging system and the BONANZA detector we observed 24 e+e-→e+e-e+e- events in agreement with the expected number from QED. We observed no e+e-→e+e- + hadrons event, and present an upper limit for the partial width Γη′→γγ of 11.5 keV (95% CL) which is evidence against the Han-Nambu quark model. © 1979.
