γ-ray Compton scattering has been applied to study the electronic state of electro-deposited and melt-quenched amorphous Ni_P_ alloys, and electro-deposited amorphous Co_P_ alloy. Based on experimental Compton profiles, it is conclused that the charge transfer occurs from phosphorus atom to 3d band holes of transition metals, but 3d states may not be completely filled with electrons even in amorphous Ni_P_ alloy
