Resonance production by two-photon interactions at SPEAR
Two-photon interactions have been studied with the SLAC-LBL Mark II magnetic detector at SPEAR. The cross section for production by the reaction e+e-e+e- has been measured at beam energies from 2.0 to 3.7 GeV. The radiative width () has been determined to be 5.81.1 keV (20% systematic uncertainty). Upper limits on the radiative widths of the f(1270), A2(1310), and f(1515) tensor mesons have been determined. A search has been made for production of the E(1420) by collisions, but no signal is observed. © 1983 The American Physical Society.
