Abstract
The valence electronic charge density is calculated for aluminum from wave-functions obtained via Ashcroft's pseudopotential. A contour plot of the charge density is presented in the (100) plane. The Fourier transform of the charge density is used to calculate the atomic form factors which are compared with experimental X-ray form factors. The accuracy of the wavefunctions are further tested by comparing calculations of the imaginary part of the frequency dependent dielectric function with and without the effect of core states.
