The reaction γγ→3 π+3 π- has been studied usig the JADE detector at PETRA. The topological cross section σ(γγ→3 π+3 π-) was measured in the CM energy range 1.5-5.5 GeV. The production of ρ0,s was observed and the average number of ρ0,s per event measured. The contributions of the subprocesses γγ→ρ02 π+2 π-, γγ→ρ0ρ0π+2 π- and γγ→ 3 π+3 π- (phase space) were studied and 95% C.L. upper limits for the cross section σ(γγ→ρ0ρ0π+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.
