The
nuclear magneton (symbol <math>\mu_p</math>), is a
physical constant of
magnetic moment[?], defined by:
- <math>\mu_p = {{e \hbar} \over {2 m_p}}</math>
where:
- <math>e</math> is the elementary charge,
- <math>\hbar</math> is the Dirac's constant,
- <math>m_p</math> is the proton rest mass
In the SI system of units it's value is approximately:
- <math>\mu_p</math> = 5.050 786 6(17) × 10-24 J·T-1
