Measurements of the magnetic anisotropy in pure nickel after fast neutron irradia-tion at 5 K and after successive isochronal annealings at various temperatures be-tween 5 K and 300 K were carried out at liquid helium temperature. Observed torquecurves after the irradiation consist of only a biaxial component. By analyzing the in-tensity and phase of the biaxial term after the irradiation and during isochronal annealings, it was found that the structure of interstitials in nickel is 100-dumbbell typeand those interstitials are initially aggregated on (100) planes, then change their stategradually and finally onto (111) plane after isochronal annealings at 320 K. The in-tensity of induced torque curves in nickel was compared witlt the case of bcc iron.
