Half of the heavy elements including all actinides are produced in r-process nucleosynthesis whose sites and history still remain a mystery. If continuously produced, the Interstellar Medium (ISM) is expected to build up a quasi-steady state of abundances of short-lived nuclides (with half-lives ≤100My), including actinides produced in r-process nucleosynthesis. Their existence in today’s ISM would serve as a radioactive clock and would establish that their production was recent. In particular...[Show more]
