A point defect with long‐range interaction changes the dynamical matrix of the ideal crystal in infinitely many elements. The method for the evaluation of the local modes and of the Green's function of this problem proposed earlier is extended in order to apply it to the case when interstitials are present. The use of some more general formulae enables the final formulae to be stated in a surprisingly clear form.
