The transverse component of the dynamic form factor of the two-dimensionaldilute Ising-like ferromagnet with nearest neighbor exchange interactions atabsolute zero temperature is obtained by using a perturbation method developedby the authors. The dynamic form factor has a five-peak structure for everywave number and concentration, The dynamic form factor for finite-size systemsis also calculated by a computer. The results obtained by the perturbation theoryare in fairly good agreement with those for finite-size systems.
