|
Strong Nuclear Force |
One of the four fundamental forces that act on hadrons, holding nucleons together. Has a short range of a couple femtometers |
|
|
Antiparticle |
The antimatter counterpart of a particle, with exactly the same rest mass but opposite charge. |
|
|
Hadrons |
A particle/antiparticle that is affected by the strong nuclear force, and if it has charge then the electrostatic force too |
|
|
Leptons |
A fundamental particle that isn't affected by the strong nuclear force |
|
|
Baryon |
A hadron made up with three quarks |
|
|
Meson |
A hadron made up of a quark and an antiquark |
|
|
Beta minus decay |
The decay of a neutron in an unstable nucleus into a proton, an electron and an electron-antineutrino (UDD -> UUD) |
|
|
Beta plus decay |
The decay of a proton in an unstable nucleus into a neutron, a positron and an electron-neutrino (UUD->UDD) |
|
|
Resultant Force of a Nucleon |
The vector sum of the attractive strong nuclear force and the repulsive electrostatic force |
|
|
Equilibrium Separation (ro)
|
The distance at which the resultant force between two nucleons is zero |
