A Spin parity analysis of gamma gamma ---> rho+ rho-

A spin-parity analysis of the ϱ + ϱ − system in the reaction γγ→ϱ + ϱ − →Π + Π − Π 0 Π 0 has been performed using the ARGUS detector at the e + e − storage ring DORIS II at DESY. The cross section is found to be dominated by the amplitudes J P = 0 + and J P = 2 + ( J z = 2).
