The reactionγγ→3π +3π - has been studied usig the JADE detector at PETRA. The topological cross sectionσ(γγ→3π +3π -) was measured in the CM energy range 1.5–5.5 GeV. The production ofρ 0,s was observed and the average number ofρ 0,s per event measured. The contributions of the subprocessesγγ→ρ 02π +2π -,γγ→ρ 0 ρ 0 π +2π - andγγ→ 3π +3π - (phase space) were studied and 95% C.L. upper limits for the cross sectionσ(γγ→ρ 0 ρ 0 π + π - determined. Finally the Bose-Einstein correlation for pairs of like signed pions was observed. A fit to a standard parametrization gave results consistent with other studies of this effect in pion systems.
