Nuclear magneton

The nuclear magneton (symbol μN) is a physical constant of magnetic moment, defined in SI units by: μ N = e ℏ 2 m p {\displaystyle \mu _{\text{N}}={{e\hbar } \over {2m_{\text{p}}}}} and in Gaussian CGS units by: μ N = e ℏ 2 m p c {\displaystyle \mu _{\text{N}}={{e\hbar } \over {2m_{\text{p}}c}}} where: e is the elementary charge, ħ is the reduced Planck constant, mp is the proton rest mass, and c is the speed of light Its CODATA recommended value is: In Gaussian CGS units, its value can be given in convenient units as The nuclear magneton is the natural unit for expressing magnetic dipole moments of heavy particles such as nucleons and atomic nuclei.
