DESY-PETRA. PLUTO Collaboration. Measurement of cross sections for four charged pions in photon-photon collisions for non-tag and single-tag events. Process is dominated by 2RHO0 production with rapid rise in cross section around W = 1.2 GeV. Spin parity analysis of 2RHO0 system shows JP = 2+ to dominate, though 0+ is also possible for W& lt;1.4 GeV. Negative parity states are excluded.
