Abstract
Single crystals of Ni were irradiated with 137 MeV xenon ions (Xe 10+) of fluences up to 4.9 × 1013 ions/cm 2 below 13 K. After the irradiation, the X-ray cryostat with the specimens was transferred from an irradiation chamber to the X-ray diffraction equipment below 20 K. The results of X-ray diffuse scattering near Bragg reflections at low temperature indicate that the defects are located in cascades and suggest that a small amorphous zone exists within the cascade region. By the thermal annealing at 40 K corresponding to the recovery stage IA, the defects in the cascades rearrange.
