The latter nuclides are astrophysically important in that they may have been involved in the production of the 22Ne (Ne‐E) and 26Mg enrichments identified ... 467 ———. 1985, in Nucleosynthesis: ...

We use isotopic measurements to fingerprint different modes of nucleosynthesis, to time and determine rates ... and we have developed several extinct isotope systems (e.g. 26Al – 26Mg) to this end.
