AbstractAbstract

[en] Data collected in the experiment R704 at the CERN ISR are used to study the annihilation process anti pp→π⁰π⁰ at several centre-of-mass energies between 2.97 and 3.56 GeV. A total sample of 7359 events has been identified, from which cross sections and angular distributions in the interval 0< vertical strokecosθ*vertical stroke<0.5 have been measured. (orig.)
