Analysis of the spreading width of the particle-hole giant resonances
We evaluate the spreading width of the giant resonances using the discontinuity in the second derivative of the propagator of the vibrational phonon. This allows us to isolate the processes that contribute to the spreading width in terms of the Feynman diagrammatic expansion of the full boson propag...
