Meaning and Definition
The antiparticle of the neutron.
A subatomic particle with the same mass as a neutron but opposite baryon number, magnetic moment, and other quantum numbers. When an antineutron and a neutron collide, they annihilate, producing energy and other particles.

FAQ
Frequently Asked Questions
Yes, an antineutron is composed of one anti-up quark and two anti-down quarks, the antiparticle counterpart to the neutron's two down and one up quark.
Naturally occurring antineutrons are extremely rare and short-lived, as they annihilate almost instantly upon contact with ordinary matter. They are primarily produced in high-energy particle accelerators or in cosmic ray interactions.
Like the neutron, the antineutron is electrically neutral (has zero electric charge). The difference lies in other quantum numbers, such as baryon number.
They are detected indirectly by observing their annihilation products (like pions and gamma rays) or by analysing their interactions in specialised particle detectors within controlled experimental setups.
The antiparticle of the neutron.
Antineutron is usually formal, technical, scientific in register.
Antineutron: in British English it is pronounced /ˌæn.tiˈnjuː.trɒn/, and in American English it is pronounced /ˌæn.t̬iˈnuː.trɑːn/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think 'ANTI-NEUTRON' = Against a Neutron. Like matter's opposite, it's the 'evil twin' in a science story that annihilates on contact.
Conceptual Metaphor
Mirror image / Opposite twin (used in popular science to explain antimatter).
