When we perform a resonant expansion of φ and substitute such expansion in the expression for Γ, we obtain a contribution that is associated exclusively with the resonant state, and other contributions that involve ... WebMay 4, 2010 · Decay width is expressed in energy units, MeV (million electron volts), not time units like ‘mean lifetime’. (Of course mass can be expressed in energy units because m = E / c^2, so maybe the term is a mass.) Also, thank you Rajini for addition bit of info.
