Abstract: (Physical Society of Japan)

The measurement of gamma rays from the diffuse afterglow of radioactivity originating in massive-star nucleosynthesis is considered a laboratory for testing models, when specific stellar groups are investigated, at known distance and with well-constrained stellar population. Regions which have been exploited for such studies include Cygnus, Carina, Orion, and Scorpius–Centaurus. The Orion region hosts the Orion OB1 association and its subgroups at about 450 pc distance. We report the detection of l gamma rays from this region with INTEGRAL/SPI.
