The magnetic field dependence of the conduction band to acceptor (e, A°) transition involving the acceptor carbon is analyzed in high‐purity p‐type GaAs at very low and very high excitation intensities. The change in the density of states of the free electrons with magnetic field determines the lineshape and the non‐linear peak shift of these transitions. From the observed splitting into different electron Landau levels an effective mass of m * / m 0 = 0.0663 ± 0.006 is determined. The variation of the low‐energy wing of the luminescence line with magnetic field gives an effective mass of m * / m 0 = 0.0669 ± 0.0006 if the effect of a linear Zeeman splitting is included.
