✦ Synopsis

The transverse magnetoresistivity AO/Oo and the low-fieM Hall coefficient Ro were measured in aluminum containing dilutely concentrated Cu impurities. It is found that the low-field Hall coefficient Ro is positive, in contrast to the isotropic value, which is negative. The large and positive values of Ro are due to the conduction electrons of aluminum that suffer an anisotropic scattering on the copper impurities. The simultaneous low-field magnetoresistance and Hall coefficient measurements, combined with the simple equations derived by Kesternich, permitted us to determine the anisotropy of the electronic scattering in terms of the mean free path ratios 1++/1_ and 1__/1_.
