    "abstract": "Threshold neutral pion photoproduction on light nuclei is studied in the\nframework of baryon chiral perturbation theory. We obtain a general formula for\nthe electric dipole amplitude in the special case of neutral pion\nphotoproduction on a nucleus. To third order in small momenta, the amplitude is\na sum of 2- and 3-body interactions with no undetermined parameters. With\nreasonable input from the single nucleon sector, our result for neutral pion\nphotoproduction on the deuteron is in agreement with experiment.",
