The relatively short half-life of such odd-odd heavy isotopes means that they are not available in quantity and are highly radioactive.
12.
Many heavy isotopes, most notably californium-252, also emit prompt neutrons among the products of a similar spontaneous radioactive decay process, spontaneous fission.
13.
Urey and Murphy calculated from the Debye model that the heavy isotope would have a slightly higher boiling point than the light one.
14.
Most neutron emission outside prompt neutron production associated with fission ( either induced or spontaneous ), is from neutron-heavy isotopes produced as fission products.
15.
Because kinetic isotope effects typically favor transformation of light isotopes ( e . g ., ), heavy isotopes ( 13C ) become enriched in residues.
16.
In theory, radioactive heavy isotopes of the elements could be used for such labeling; this was the case in many early applications of the method.
17.
:: It's also possible to get water with a heavy isotope of oxygen ( up to 2 extra neutrons ) to make even heavier water.
18.
Instead, scientists rely on the process that powers hydrogen bombs : the joining together of two heavy isotopes, or forms, of hydrogen : deuterium and tritium.
19.
This is because as the number of atoms in a molecule increases, the probability that the entire molecule contains at least one heavy isotope atom also increases.
20.
Shaped like a torus, the " George " device had a small amount of heavy isotopes of liquid hydrogen ( deuterium and tritium ) placed at its center.
