Cherenkov mass inference
= Cherenkov mass inference
{c}
The cone relation $\cos\theta=1/(n\beta)$ determines speed. Together with a measured <kinetic energy> $T$, the rest <mass> is $m=T/[(\gamma-1)c^2]$. The inference requires the radiation to be identified as <Cherenkov radiation>, and the frequency-dependent <phase refractive index> must be known.
