As a test case, the ground state of $Pb_{2}$ has been studied, both with and without relativistic corrections. Ab initio values of $r_{e}, \omega_{e}, \omega_{e}x_{e}$ and the value of $D_{e}$ corresponding to dissociation to two $^{3}{P_{_{o}}}$ atoms are reported. Although direct relativistic effects are large, the indirect effects are small compared to electron correlation. For the ground state the nonrelativistic approximation gives good agreement with available experimental results. en_US dc.format.extent 52196 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MULTICONFIGURATION EFFECTIVE POTENTIAL CALCULATION OF THE SPECTROSCOPIC CONSTANTS OF $Pb_{2}$ en_US dc.type article en_US
