Abstract
The Raman spectrum of the Zn acceptor in GaP is examined under applied magnetic fields and uniaxial stress. The relative intensity and Zeeman splitting of the prominent B-line are not consistent with previous conjectures that it is the transition between the acceptor ground states associated with the P3/2 and P1/2 valence-band maxima. An alternative interpretation of this feature based on the coupling of the acceptor bound states of the two bands by the acceptor impurity potential is suggested.
