    "abstract": "We have studied the pion^{-} capture in nuclei leading to two photons, using\nimproved many body methods which have been tested with success in one photon\npion^{-} radiative capture, muon^{-} capture and neutrino scattering. The\nqualitative features of the experimental data are reproduced but there are\nstill some disagreement at small relative photon angles. The reaction is a\npotential source of information on details of the gamma-gamma-pion-pion vertex\nwhere chiral corrections can be relevant. New and more precise experiments are\nplanned which make calculations like the present one relevant and opportune.\n---------------------------------------------------------",
