hi
i am looking for the correct equation, that gives me the linewidth by knowing the time of the emission process.
so far, i found in the internet:
Δf=1/(Δt), Δf=1/(4πΔt) and Δf=1/(2Δt)
can you tell me, when i have to use which of these equations and maybe whether you think that these equations are correct?
sry for my english, still practising! ;-)
