The samples were irradiated with 150MeV P ions, at 30K, to doses of 1.6 x 1014 or 4.1 x 1014/cm2, and the resultant defect structures were studied at room temperature using diffuse X-ray scattering methods. The scattering experiments showed that both interstitial and vacancy dislocation loops coexisted in the pure Ni and alloys. The size distribution of the dislocation loops was analyzed by fitting the theoretical scattering intensities of the dislocation loops to the experimental ones.
