Electron’s Distribution in Liquid IIIb-Metals

抄録

The structure factors of liquid Ga at 50°C and liquid Tl at 315°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 been calculated. The difference of electron distribution between the same valent IIIb-metals are also discussed.
