- Tritium is also produced in heavy water-moderated reactors whenever a deuterium nucleus captures a neutron.
- This is why brown dwarfs (so-called failed stars) cannot utilize ordinary hydrogen, but they do fuse the small minority of deuterium nuclei.
- For instance, when two deuterium nuclei fuse, they often produce helium-3 and a free neutron.
- The figure on page 28 shows the make-up of these simplest nuclei and illustrates what happens when two deuterium nuclei collide.
- Palmer believed that the helium-3 in the atmosphere comes from the fusion of two deuterium nuclei or 'deuterons'.
- Its final energy for protons, and later deuterium nuclei, was 10 G eV.
