The mesons have been identified via the $\\omega \\rightarrow \\pi^0 \\gamma \\rightarrow 3 \\gamma$ and $\\eta^\\prime\\rightarrow \\pi^0 \\pi^0\\eta \\rightarrow 6 \\gamma$ decays, respectively, registered with the CBELSA/TAPS detector system. From the measured meson momentum distributions the momentum dependence of the transparency ratio has been determined for both mesons.
