TEST OF THE RELATIVISTIC 1S WAVEFUNCTIONS IN AU AND PB USING EXPERIMENTAL COMPTON PROFILES

Compton profiles were measured in Pb and Au up to a momentum of 110 au using 412 keV gamma radiation. The interpretation of the measurements is limited to the momentum range between 60 and 110 au, which is sensitive to the core electrons and which also contains the K- and L-shell binding edges resolved in the present experiment. The energy dependence of the Compton scattering cross section is described using the expression given by Ribberfors (1975) and good agreement is found between experiment and the relativistic Hartree-Fock Compton profiles calculated by Biggs (1975) and colleagues.
