antinucleons
Antinucleons are the antiparticles of nucleons. Nucleons are the particles that make up atomic nuclei, namely protons and neutrons. Therefore, an antinucleon is either an antiproton or an antineutron.
Antiprotons have the same mass as protons but carry a negative electric charge instead of a positive
When an antinucleon encounters its corresponding nucleon, they annihilate each other, releasing a significant amount of
The existence of antinucleons was predicted by theoretical physicist Paul Dirac in his relativistic theory of
Antinucleons are produced in high-energy particle collisions, such as those that occur in particle accelerators or
