Plutonium-238 is synthesized by bombarding uranium-238 with deuterons ( D, the nuclei of heavy hydrogen ) in the following reaction:
12.
The nuclei of the heavy hydrogen isotopes deuterium and tritium contain one proton bound to one and two neutrons, respectively.
13.
The Heisei Mechagodzilla is powered by a nuclear reactor, deriving its energy from heavy hydrogen and helium-3 in pellet form.
14.
As a specific example, the hydrogen isotope deuterium ( heavy hydrogen ) is almost double the mass of the common hydrogen isotope.
15.
The accelerator was used to fire heavy hydrogen nuclei ( " deuterons ", which Rutherford called " diplons " ) at various targets.
16.
Deuterium ( " heavy hydrogen " ) already has the extra neutron that light hydrogen would absorb, reducing the tendency to capture neutrons.
17.
Urey and his colleague George Murphy calculated the redshift of heavy hydrogen from the Balmer series and observed very faint lines on a spectrographic study.
18.
An atomic nucleus of heavy hydrogen, or deuterium, consists of a proton and a neutron; an ordinary hydrogen nucleus contains only one proton and no neutrons.
19.
With the equipment he was able to produce intense beams of protons and of the nuclei of heavy hydrogen, and then study their interactions with light nuclei.
20.
Tritium is generated in the fuel of all reactors; however, CANDU reactors generate tritium also in their coolant and moderator, due to neutron capture in heavy hydrogen.
