We give a strong-coupling real-frequency-axis formulation of the phonon-self-energy change on entering the superconducting state for a [ital d]-wave superconductor. The effect of impurity scattering in the Born (weak scattering) and unitary ([ital T]-matrix approach) limits is considered and numerical results presented for phonon shifts and changes in width.
