Transport Cross Sections:
The transport cross section (TCS) is calculated from the differential elastic-scattering cross sections. The latter were calculated using the relativistic Dirac
partial wave analysis, as described by Walker . The scattering potential was obtained from the self-consistent Dirac-Hartree-Fock electron density for free atoms 
with the local exchange potential of Furness and McCarthy . The numerical calculations were performed with the algorithm described by Salvat and Mayol .
