We study the mechanism for this reaction, where we consider that the elementary reaction in Nb nucleus proceeds as $ \\gamma N \\to \\omega N; ~ \\omega \\to \\pi^0\\gamma $. The $\\omega$ meson photoproduction amplitude for this reaction is extracted from the measured four momentum transfer distribution in the $ \\gamma p \\to \\omega p $ reaction.
