摘要
Relativistic configuration-interaction calculations have been made for the 6p2 resonances of Hg I using a relativistic version of the Fano theory. Pair-correlation effects associated with the 5d and valence electrons are important, contributing approximately 1.5 eV to the positions of the resonances. Relative to Hg 6s2, the theoretical positions of the resonances (in cm-1) are 90654, 94959, 97066, 106257, and 111 609 for P-3(0,1,2), D-1(2), and S-1(0). The experimental values are 90 096, 93 980, 96 185, and (tentatively) 103 232, 109 286 cm-1. The theoretical values for the width (in eV) are 0.002, 0.0, 0.215, 0.914, and 0.298. The experimental value for the P-3(2) width is 0.272 +/- 0.074 eV.
