Definition

1. Noun:
   • The antiparticle of a neutron: An antineutron is the antimatter counterpart to a neutron. It has the same mass as a neutron but opposite quantum numbers, such as baryon number.

Examples of Usage

• Noun:
  • Scientists detected an antineutron in the particle accelerator.
  • The collision produced a neutron-antineutron pair.

Advanced Usage

• "Neutron-antineutron oscillation": A hypothetical process in particle physics where a neutron transforms into an antineutron and vice-versa.
  • Research into neutron-antineutron oscillation could explain matter-antimatter asymmetry.

Variants and Related Words

• Antiparticle (n): A subatomic particle with the same mass as another particle but opposite electric or magnetic properties.
  • The positron is the antiparticle of the electron.
• Antimatter (n): Matter composed of antiparticles.
  • Antihydrogen is an atom of antimatter.

Synonyms

• Neutron antiparticle: The antiparticle corresponding to a neutron.

Related Phrases

• "Antineutron annihilation": The process where an antineutron collides with a neutron or other matter particle, resulting in their mutual destruction and release of energy.
  • The energy released from antineutron annihilation is immense.
