Positron

Top Articles

Positron - The positron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1, a spin of 1/2, and the same mass as an electron.

Positron emission - Positron emission is a type of beta decay, sometimes referred to as "beta plus" (β+). In beta plus decay, a proton is converted to a neutron via the weak nuclear force and a beta plus particle (a positron) and a neutrino are emitted.

Positron electron annihilation reaction - The positron electron annihilation reaction refers to the physical phenomena of a positron particle (the physical opposite of an electron), generated by a beta decay and slowed to "thermal speeds", and combines/reacts with an electron. The two particles completely disappear (annihilate) each other, leaving only the corresponding energy, released in a specific form; ...

Positron (game) - Positron is a video game made for the BBC Micro and Acorn Electron computers by the programmer Gary Partis, first released by Micro Power in 1983.
