Abstract (data abstract)
SLAC-PEP. (PEP-020). DELCO COLLABORATION. PION-PAIR PRODUCTION IN PHOTON-PHOTON INTERACTIONS AND A MEASUREMENT OR THE RADIATIVE WIDTH OF THE F0 MESON. QED E+E- BACKGROUND IS IDENTIFIED AND ELIMINATED. RESULTS AGREE WITH A SIMPLE MODEL OF SUPERPOSITION AND INTERFERENCE OF THE F0(1270) RESONANCE,PRODUCED WITH HELICITY 2,WITH A BORN-TERM CONTINUUM. THE WIDTH OF THE (F0--& gt;GAMMA GAMMA) IS DETERMINED TO BE 2.70 +- 0.21 KEV.
