Abstract

We propose that live 26Al in the early solar system and the large mass of 26Al (1.5 Mo) the galaxy today have different sources. By making 26Al in cores where stars form, awkward "mixing in" is avoided. We present three distinct pictures attibuting 26Al and other extinct radioactivity within molecular-cloud dense cores to cosmic-ray irradiation of those cloud cores.
