Hi all EPW users

I want to get phonon liftime due to el-ph interaction in Silicon.
I know the scattering rate is the inverse of the relaxation time but in the top
of output file of linewidth.phself written "Phonon lifetime (meV)".
I think it should be containing scattering rate not lifetime.!
I'm confused. Which one is correct? lifetime? or scattering rate?

Thank you so much,

Dear Majid,

You are correct. There is indeed a typo.
It should be written linewidth instead of lifetime.

Best,
