Hadron production by e/sup +/e/sup -/ annihilation at center-of-mass energies between 2. 6 and 7. 8 GeV

Results are presented on multihadron production by e/sup +/e/sup -/ annihilation from the Mark I and Mark II detectors at SPEAR. Other than the narrow resonances psi (3095) and psi' (3684), the total hadronic cross section varies between 36.5 and 6.4 nb over the center-of-mass energy range 2.6 to 7.8 GeV with complicated structure near 4.1 GeV not completely resolved by these measurements. Evidence for scaling of inclusive momentum distributions of hadrons is presented.
