It is now generally accepted that accretion of matter onto a compact object (white dwarf, neutron star or black hole) is one of the most efficient processes in the universe for producing high energy radiations. Measurements of the {gamma}-ray emission will provide a potentially valuable means for furthering our understanding of the accretion process. Here we focus on neutron capture processes, which can be expected in any situation where energetic neutrons may be produced and where the liberated neutrons will interact with matter before they decay (where they have a chance of undergoing some type of neutron capture). Line emission at 2.2 MeV, resulting from neutron capture on hydrogen, is believed to be the most important neutron capture emission. Observations of this line in particular would provide a probe of neutron production processes (i.e., the energetic particle interactions) within the accretion flow. Here we report on the results of our effort to image the full sky at 2.2 MeV using data from the {ital COMPTEL} experiment on the {ital Compton Gamma-Ray Observatory} ({ital CGRO}). {copyright} {ital 1997 American Institute of Physics.}
