 Reduced Compton wavelength (source code)

= Reduced Compton wavelength
{c}
{title2=$\bar\lambda_C=\hbar/(mc)$}

The <Compton wavelength> divided by $2\pi$. A massive static <propagator> produces an exponential factor $e^{-r/\bar\lambda_C}$, making this the natural range scale for a <Yukawa potential>. It is not a sharp geometric radius or a hard interaction cutoff.
