| Antimatter also exists and so there is an antiproton, an antineutron and an antielectron often called the positron. |
| If, on the other hand, there is a hydrogen ion and a positron, the end result is a proton and gamma radiation. |
| We've also requisitioned every watt of power within the city to power the positron cannon. |
