Electron's Distribution in Liquid Zinc and Lead

Abstract

The structure factors of liquid Zn at 450°C and liquid Pb at 340°C have been determined by neutron diffraction with sufficient accuracy and are compared with those by X-ray diffraction. A remarkable difference in these structure factors is clearly found around the first peak region, as well as a slight variation of the first peak position and it is apparently larger than the experimental errors, for both liquid metals. The ion-electron correlation function has been evaluated from this difference with the help of theoretical calculation of the electron-electron correlation function. By the Fourier transform of this function, the radial distribution function of valence electrons around ion has also been calculated. The ionic radii obtained in this work were equivalent to those proposed by Pauling.
