https://doi.org/10.1351/goldbook.B00692
Electromagnetic fundamental physical constant: \[\mu _{\text{B}} = \frac{e\ \mathrm{\hslash }}{2\ m_{\text{e}}} = 9.274\hspace{0.5em}0154\hspace{0.25em}\left(31\right)\times 10^{-24}\ \mathrm{J}\ \mathrm{T}^{-1}\] where \(e\) is the @E02032@, \(\mathrm{\hslash}\) the @P04685@ divided by \(2\ \pi \) and \(m_{\text{e}}\) the @E02008@.
