BONN-ELSA. Measurement of the cross sections for the reaction GAMMA P --& gt; P PI0 ETA for photon energies covering the resonance region from (P PI0 ETA) production threshold at W = 1.63 GeV to 2.5 GeV. Numerical values supplied by V. Nikonov. ; Other ; Differential cross sections as a function of the angles of combinations of final state particles for the W range 1.7 to 1.9 GeV. Errors shown are statistical only.
