| 1. | It is made of molecules consisting of oxygen and heavy hydrogen.
|
| 2. | Heavy hydrogen gas would form near one electrode, and form into diatomic molecules, right?
|
| 3. | On this sample, the Balmer lines for heavy hydrogen were seven times as intense.
|
| 4. | But as the temperature goes up, more heavy hydrogen evaporates, eventually precipitating out over Greenland.
|
| 5. | Fusion experiments also rely on heavy hydrogen, which fuses more easily, and gas densities can be moderate.
|
| 6. | Urey was awarded the Nobel Prize in Chemistry in 1934 " for his discovery of heavy hydrogen ".
|
| 7. | Princeton's contribution grew from Spitzer's suggestion that the fusion of heavy hydrogen atoms might be harnessed for peaceful uses.
|
| 8. | Urey therefore decided to delay publishing their results until he had more conclusive evidence that it was heavy hydrogen.
|
| 9. | Day by day they wait for a neutrino speeding through the earth to collide with a heavy hydrogen nucleus.
|
| 10. | Even though the neutron was not realized until 1932, Urey began searching for " heavy hydrogen " in 1931.
