A study was made to determine if the discrepancies at the second resonance (500 to 900 Mev) in pi /sup 0/ photoproduction in hydrogen are due to lack of angular and energy resolution. Single pi /sup 0/ photoproduction was detected by a coincidence between the recoil proton and one of the gamma rays from decay of the pi /sup 0/. The results correspond to a 56 deg c.m.s. angle for the pi /sup 0/, and the first conclusion is that the peak of the differential cross section is at a laboratory energy of approximately 7OO Mev and has a resonance width of the order of 50 Mev. Measurements for other c.m.s. angles will allow a more complete analysis. (T.R.H.)
