Definition:Nuclear Magneton

Definition

The nuclear magneton is a physical constant of magnetic moment:

\(\ds \mu_{\mathrm N}\)

\(=\)

\(\ds \dfrac {\E \hbar} {2 m_{\mathrm p} }\)

where:

$\E$ denotes the elementary charge

$\hbar$ denotes the reduced Planck constant

$m_{\mathrm p}$ denotes the proton rest mass

Symbol

$\mu_{\mathrm N}$

The symbol for the nuclear magneton is $\mu_{\mathrm N}$.

Its $\LaTeX$ code is \mu_{\mathrm N} .

Value

The value of the nuclear magneton is:

\(\ds \mu_{\mathrm N}\)

\(\approx\)

\(\ds 5 \cdotp 05078 \, 3699 \, (31) \times 10^{-27} \, \mathrm {J \, T^{-1} }\)

\(\ds \)

\(\approx\)

\(\ds 5 \cdotp 05078 \, 3699 \, (31) \times 10^{-24} \, \mathrm {erg \, Gs^{-1} }\)
