The composition of the early Solar System can be inferred from meteorites. Many elements heavier than iron were formed by the rapid neutron capture process (r-process), but the astrophysical sources where this occurred remain poorly understood. We demonstrate that the near-identical half-lives

陨石中的129I和247Cm限制了太阳r过程元素的最后天体来源
可以从陨石推断出早期太阳系的组成。快速中子俘获过程(r过程)形成了许多比铁重的元素,但是发生这种情况的天体物理来源仍然知之甚少。我们证明了几乎相同的半衰期
