In the fusion of deuterium and tritium nuclei to produce a thermonuclear reaction, where does the kinetic energy that is produced come from?The last stage in the fusion of hydrogen to form helium in the Sun involves the formation of an alpha particle (4He...
Both fission and fusion occur at the nuclear level, but one key difference is the split atoms result in radioactive products that are dangerous to human health and the environment. Zero radioactive waste is produced during the fusion proce...
A substantial energy barrier of electrostatic forces must be overcome before fusion can occur. At large distances, two naked nuclei repel one another because of the repulsive electrostatic force between their positively charged protons. If two nuclei can be brought close enough together, however, the...
However, fusion can occur under conditions of extreme pressure and temperature. That is why fusion reaction is often termed as thermonuclear reaction. Nuclei, which have positive charges, must collide at extremely high speeds to overcome the Coulomb barrier. The speed of particles in a gas is ...
In a hydrogen bomb, two isotopes of hydrogen, deuterium and tritium are fused to form a nucleus of helium and a neutron. This fusion releases 17.6 MeV of energy. Unlike nuclear fission, there is no limit on the amount of the fusion that can occur. Sorry, your browser doesn't support ...

Fusion powers the stars and is the most abundant form of energy in the universe. For over a century, scientists and engineers have been trying to synthesize fusion power, thereby bringing clean, cheap, and virtually limitless energy to the world. Nine countries have pooled their resources into...
This reaction can occur spontaneously in nature and can also be triggered relatively easily in certain atomic species—called fissile isotopes—such as uranium-235 in a nuclear reactor. The amount of energy released by uranium fission is enormous. One kilogram of naturally occurring uranium could, ...
The term fission was first used by the German physicists Lise Meitner and Otto Frisch in 1939 to describe the disintegration of a heavy nucleus into two lighter nuclei of approximately equal size. The conclusion that such an unusual nuclear reaction can in fact occur was the culmination of a ...
