Experimental results of magnetoconductivity in metallic n-GaAs with carrier concentration n=ND−NA=8.74×1016 cm−3 have been analyzed with the theory of the Anderson localization. It was found that the coefficient of H1⁄2 due to the localization agrees quantitatively with the theoretical prediction by Kawabata. On the other hand, we found that the value of g3 due to the Coulomb interaction was nearly 8 times larger than the calculated value. These results obtained in n-GaAs are markedly different from previous results obtained in n-InSb.
