Results are given for the Zeeman behaviour of the 1Γ + 8 and 2Γ − 8 states of Zn − in Ge for B ∥ 〈100〉 and 〈111〉. Due to the larger energy spacings between the states of Zn − relative to the neutral acceptors, the splitting pattern of 2Γ − 8 at high fields is very similar to that of group III impurities at low fields. In contrast to the shallow acceptors, the behaviour of the deep ground state of Zn − is like that of a j = 3/2 atomic state with the same splittings for both directions of field, these are determined by a single g ‐factor of value 0.5355.
