Definition

The reduced gyromagnetic ratio of a particle $P$ is its gyromagnetic ratio divided by $2 \pi$.




Symbol

The symbol for reduced gyromagnetic ratio is usually denoted $\gamma / 2 \pi$, where $\gamma$ itself denotes the gyromagnetic ratio


Dimension

Reduced gyromagnetic ratio has the dimension $\mathsf {I T M^{-1} }$.


Units

The SI unit for reduced gyromagnetic ratio is hertz per tesla: $\mathrm {Hz \, T^{-1} }$

The CGS unit for gyromagnetic ratio is hertz per gauss: $\mathrm {Hz \, Gs^{-1} }$


Conversion Factors

\(\ds \) \(\) \(\ds 1\) hertz per tesla

Terminology

The term reduced gyromagnetic ratio was invented by $\mathsf{Pr} \infty \mathsf{fWiki}$ as there appears to be no such term in common use.

As such, it is not generally expected to be seen in this context outside $\mathsf{Pr} \infty \mathsf{fWiki}$.

It is deliberately intended for this naming convention to follow the precedent of:

the reduced Planck constant, which is Planck's constant divided by $2 \pi$.
the reduced Compton wavelength, which is the Compton wavelength divided by $2 \pi$.
