Reduced Compton Wavelength of Proton

Theorem
The Compton wavelength of the proton is:

Proof
By definition, the reduced Compton wavelength $\lambdabar_{\mathrm p}$ of a proton is given as:
 * $\lambdabar_{\mathrm p} = \dfrac {\lambda_{\mathrm p} } {2 \pi}$

where $\lambda_{\mathrm p}$ denotes the Compton wavelength of the proton.

Then we have:
