| We've also requisitioned every watt of power within the city to power the positron cannon. |
| If the nucleus of the an atom has too few neutrons to be stable, however, positron emission occurs. |
| Solar neutrinos are produced when two protons fuse together to form a deuterium nucleus, a positron, and a neutrino. |
| He pressed a series of controls and fired his only projectile weapon, a positron grenade, directly behind him. |
| This is a partial list of radionuclides that decay by positron emission and have been used in biomedical imaging studies. |
| Soon, we produced antiprotons in accelerators and finally, in 1995, we combined a positron with an antiproton to produce an antimatter atom. |
