Abstract
The far-infrared absorption spectra of quenched germanium were measured with the magnetic field parallel to the and crystallographic orientations. The ground states of both SA1 and SA2 acceptors, which are observed among the quenched-in acceptors, are split into two levels corresponding to states with quantum numbers of ±1/2 and ±3/2. It is concluded that D and C bands, the absorption bands for the acceptors, are due to transitions from the \varGamma8 + ground state to the \varGamma8 - and \varGamma7 - excited states, respectively. The quantum numbers of the Zeeman splitting states concerning the transitions of the D and C bands and the g-factors of these excited states for SA1 and SA2 acceptors were determined. The Zeeman splitting of the ground state is negligible compared with those of the excited states.
