  We report the first observation of the doubly-radiative decay mode of pionic
hydrogen (pi- p --> gamma gamma n) and and deuterium (pi- d --> gamma gamma X)
using the RMC pair spectrometer at TRIUMF. The process is interesting in the
context of the pi-Compton scattering and the chiPT predictions of the pion
polarizability We present our preliminary values for the B.R.(pi- p --> gamma
gamma n)=3.8x10^-5 and B.R.(pi- d --> gamma gamma X)=1.6x10^-5. Our pi- p data
indicates the dominance of pi pi --> gamma gamma mechanism. The pi- d data
shows no evidence for the d1* dibaryon.
