Abstract (from CDS):

COMPTEL, the imaging telescope on the Compton Gamma-Ray Observatory, has detected 1.809MeV gamma-ray line emission attributed to radioactive 26Al from the nearby Vela region. The location of the emission feature suggests an association with the Vela supernova remnant. The measured flux of 3.6(±1.2)x10–5ph/cm2/s is consistent with theoretical estimates for nucleosynthesis of core collapse supernovae, if the distance to the Vela supernova remnant is below 500 pc.
