Abstract An investigation is made of the range of validity of the Kohler rule for the transverse magnetoresistance of aluminium at 4.6°K by introducing structural defects with different concentration and configuration by low temperature reactor irradiation and subsequent annealing. – During irradiation the Kohler rule is extremely well satisfied, because in this case only the concentration of identical defects is enlarged. After step‐annealing, however, there are large deviations, because the structural defects not only recombine but also rearrange to other configurations, which corresponds to a change in the mean scattering anisotropy. The influence of small angle scattering is to be seen well in the measurement curves.
