The differential cross section for [sup 2]H([gamma],d)[pi][sup 0] has been measured at deuteron center-of-mass angles of 90[degree] and 136[degree]. This work reports the first data for this reaction above a photon energy of 1 GeV, and permits a test of the apparent constituent counting rule and reduced nuclear amplitude behavior as observed in elastic [ital ed] scattering. Measurements were performed up to a photon energy of 4.0 GeV, and are in good agreement with previous lower energy measurements. Overall, the data are inconsistent with both constituent-counting rule and reduced nuclear amplitude predictions. [copyright] [ital 1999] [ital The American Physical Society]
