| electrons | Stable elementary particles having the smallest known negative charge, present in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons around atomic nuclei determine the chemical identities of elements. Beams of electrons are called cathode rays or beta rays, the latter being a high-energy biproduct of nuclear decay. (12 Dec 1998) |

| runaway electrons | <radiobiology> Those electrons in a plasma that gain energy from an applied electrical field at a faster rate than they lose it through collisions with other particles. These electrons tend to run away in energy (not position) from the cooler remainder of the background plasma, because the collision cross-section decreases as the particle's velocity increases, so that the faster the particle goes, the less likely it is to be stopped. See: collision cross-section. (17 Dec 1997) |
