                      Green function method we study the electronic and magnetic
                      properties of NiMnSb and similar Heusler alloys. We show
                      that all these compounds are half-metals, e.g. the
                      minority-spin band is semiconducting and the Fermi level
                      falls within this gap resulting in $100\%$ spin polarization
                      at the Fermi level. The total spin moment M(t) shows the
                      so-called Slater-Pauling behaviour and scales with the total
                      valence charge Z(t) following the rule M(t) = Z(t) - 18 for
                      half and M(t) = Z(t) - 24 for full Heusler alloys. These
                      rules are connected to the origin of the gap. Finally we
                      show that the inclusion of the spin-orbit interaction in our
                      calculations kills the half-metallic gap but the
                      spin-polarization at the Fermi level can be still very high,
                      approximately $99\%$ for NiMnSb, but much lower for a
                      half-metallic compound like zinc-blende MnBi $(77\%).$},
