All quantities entering in the form factors have been calculated from first principles, including the position of the $d$ resonance. The full nonlocal character of both the ordinary pseudopotential terms and the additional hybridization terms is included without approximation. To first order, the orthogonalization hole has also been treated exactly. The Kohn-Sham approximation is used for the conduction band-core exchange, while exchange among conduction electrons is included through a modified dielectric function. The effects of electron correlation and crystal-field splitting are neglected. The calculated form factors are used to estimate the band gap at the $L$ point and to calculate the resistivity of the liquid metal with good results. It is expected that the form factors will be useful in further calculations of the electronic properties of the noble metals.Read More
