Abstract:	From 3500 γ's observed in the 4.7 m HBC MIRABELLE at Sepukhov, we obtain the dependence on n_? of the average number of produced π^0,s, 〈n₀〉, and the π⁰π⁰ correlation parameter, $?_{2}^{00}$ . We present also the $?_{2}^{??}$ and $?_{2}^{+0}$ parameters and information concerning KNO scaling. Various momentum distributions are given. The invariant γ cross sections distributions are compared with corresponding data at other energies.

Keywords:	France - Soviet Union Collaboration
