^kv The effect of

**spin**-**orbit**coupling is introduced assuming that also the**spin**-**orbit**interaction HK is a perturbation. Now, according to the Dirac theory of theelectron, indicating by o the Pauli spin matrices and if p is the momentum

The bands without

energy surfaces do not deviate much from sphericity near the origin, one can

conclude that there are two types of holes in Ge, with different effective masses.

The bands without

**spin**-**orbit**interaction are also given for comparison. Since theenergy surfaces do not deviate much from sphericity near the origin, one can

conclude that there are two types of holes in Ge, with different effective masses.
