Abstract (from CDS):

We report the negative results of our searches in COMPTEL data for 1.809MeV gamma-ray line emission from four localized regions which contain nearby supernova remnants (SNRs). The upper flux limits (2σ) are found to be in the range of 1.4x10–5 to 2.4x10–5photons/s/cm2. These upper limits do not severely constrain the theoretical 26Al yields from individual core collapse supernovae due to large uncertainties in the SNR distances and the nature of the progenitor stars.
