From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Nuclear reaction kinematics are customarily performed in units involving the electronvolt, a consequence of accelerator technology.

The difference in mass, 0.0011, then represents the binding energy of the two particles and corresponds to 1 million electron volts. They do, however, involve atomic transitions of only a few electron volts, indicating that any non-linearities in the quantum formalism must be very small. Temperatures of isocontours are given in electron volts. The energy of the accelerated electrons reached up to over mega electron volts. At stagnation the density is high and the temperature is about several hundred electron volts, so that the electrons and ions equilibrate giving equal ion and electron temperatures. In our experimental conditions, assuming again a temperature of a few tens of electron volts, a calculation of radiation conductivity yields a value which is comparable to electron thermal conduction. Since the current is now constricted to flow in a very narrow region near the axis, the electron temperature in this neck reaches several hundred electron volts. The essential idea behind this scheme is to assemble the fuel with sufficient density to sustain fusion burn, but with a low and uniform temperature a few hundred electron volts!. He then calculated the energy of this undiscovered resonance to be 7.6 million electron-volts. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. When the gas temperature reaches over 16 electron-volts, the gas ionizes into ions and electrons. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As frequency increases beyond visible into the ultraviolet, photons now carry enough energy (about three electron volts or more) to excite certain doubly bonded molecules into permanent chemical rearrangement.
