Data on the atomic form factor: Computation and survey

This paper prese nts the res ults of ca lculations of atomic form factors, based on tables of electron charge di stribu tio ns co mpu ted from Hartree wave functions, for a wide ran ge of atomic numbers. Co mpu tations of t he form fa ctors for fi ve elements-carbon , oxygen , iron , arsenic, and mercury-are prese nted and a method of interpolation for other atoms is indicated. A s urvey of previous results is given and the relativistic t heo ry of Rayleigh scattering is reviewed. Comparisons of the present res ults with previous compu tations and with some sparse experi me ntal data are made.
