The nuclear magneton, a physical constant of magnetic moment, is the natural unit for expressing magnetic dipole moments of heavy particles such as nucleons and atomic nuclei.
This constant is the nuclear magneton, `mu_N`, divided by the product of the speed of light and Planck's Constant and is represented in units of 1/(m/T)
This constant is specified with a standard uncertainty (standard deviation) of: 0.000000056E-2 `1/(m*T)`
