概要 An experiment for photoproduction of 2π^0 and other neutral mesons has been performed at the SPring-8/LEPS beam line. A forward gamma detector (FG) newly constructed has been used in combination with the backward gamma detector (BG). The energy calibration of the forward gamma detector has been made by an iteration method applied for 2γ forming π^0. The obtained π^0 mass resolution is 4.9% for now. The invariant mass distributions for 2 and 3 gamma event data are also shown for preliminary results.
