A doublet observed for the G line of Zn (0) without applied perturbation is attributed to relative shifts of the two Γ − 4 states which are part of the compound excited state of this transition. This effect also increases the energy spacing between the G doublet and the rest of the lines of the Lyman series. The energies and widths of all the lines are temperature dependent at temperatures where group III lines no longer show these effects. Zeeman measurements have demonstrated conclusively that the low temperature Lyman series of Zn (0) in Ge arises from the 1Γ + 1 ground state. These studies also establish that the Zeeman excited states of Zn (0) are compounded from wave functions identical to those of the ground state of Zn − and the excited states of group III acceptors in Ge.
