摘要：

Various mixtures of r-, p- and s-nucleosynthesis products have been observed in the isotopes of tellurium, xenon and krypton extracted from mineral separates of the Allende meteorite. The presence of several isotopically distinct components in these high Z elements and the close association of isotopically normal low Z elements with particular isotopes of the high Z elements suggest that our Solar System may have formed directly from the debris of a single precursor star, approximately concentric with the present Sun. © 1979 Nature Publishing Group.
