摘要：

Energy-dependent global Dirac optical model potentials are found by fitting proton elastic scattering data in the energy range 20-1040 MeV for C-12, O-16, Ca-40, Zr-90, and Pb-208. Three different energy- and atomic-mass-number-dependent global Dirac optical potentials are also obtained. A number of characteristic features of the potentials are discussed. In addition, the mean free path, the effective mass m(e)*, the Dirac mass M*, and the relativistic energy shift E* are calculated.
