The reaction gammad --> pi (0)X has been measured with TAPS at MAMI in the energy range E(gamma) = 140-300 MeV. Using the Glasgow tagging spectrometer a photon energy resolution of 0.8 MeV was achieved. The energy excitation functions of integral and differential total cross-sections show no structures of statistical significance > 2 sigma. Upper limits for the production of narrow isoscalar or isovector dibaryons with masses m less than or equal to 2100 MeV/c(2) were deduced.
