“neutron”的概念、定义、翻译、参考文献-科学参考

neutron

Physics

A neutral hadron (see elementary particles) that is stable in the atomic nucleus but decays into a proton, an electron, and an antineutrino with a mean life of 12 minutes outside the nucleus. Its rest mass (symbol m_n) is slightly greater than that of the proton, being 1.674 9286(10)×10⁻²⁷ kg. Neutrons occur in all atomic nuclei except normal hydrogen. The neutron was first reported in 1932 by James Chadwick.

Astronomy

A subatomic particle that is present in the nuclei of all atoms except the lightest isotope of hydrogen. It has a slightly greater mass than the proton and zero charge. Neutrons are stable in the atomic nucleus, but outside it they undergo beta decay to produce a proton, an electron, and an antineutrino. Neutrons are hadrons.
