Abstract
With the SPI high-resolution spectrometer on INTEGRAL, new results have been obtained for long-lived radioactive 26Al and 60Fe in our Galaxy: 26Al sources apparently share the pattern of Galactic rotation in the inner Galaxy, and thus allow to estimate a total mass of 26Al in the Galaxy of 2.8M⊙ from the measured flux. 60Fe production in massive stars is constrained by recent gamma-ray detections, and appears to be lower than predicted by standard models. We show the broader implications of these findings both for the study of our Galaxy, and for nucleosynthesis in massive stars.
