| 1. | Decay chain says that the first stable decay product is 210 Pb-lead.
|
| 2. | Other isotopes of thorium occur in the thorium and uranium decay chains.
|
| 3. | That summer, GSI tried and failed to find a 118 decay chain.
|
| 4. | And checking that the decay matched the decay chain of the nuclei.
|
| 5. | With four additional decay chains, the discoveries seemed more solid than ever.
|
| 6. | They occur in the decay chains of primordial isotopes of uranium or thorium.
|
| 7. | Its decay chain is the thorium series eventually ending in lead-208.
|
| 8. | Radioactive decay often proceeds via a sequence of steps ( decay chain ).
|
| 9. | Also, I don't see Uranium 238 as any of the tables on decay chain.
|
| 10. | Bismuth-213 can be obtained in what physicists describe as a decay chain from uranium-233.
