Phys. Rev. A 79, 042713 (2009) [9 pages]Fully relativistic B-spline R-matrix calculations for electron collisions with mercuryReceived 21 February 2009; published 28 April 2009 Results from a fully relativistic 36-state Dirac B-spline R-matrix (close-coupling) calculation for e-Hg collisions are reported. Angle-integrated and angle-differential cross sections for elastic scattering and excitation of the (6s6p) 3P0,1,2o and (6s6p) 1P1o states are compared to experimental data and predictions from other theories. We generally obtain a significant improvement in the agreement between experiment and theory compared to previous distorted-wave and close-coupling attempts, in particular, for the near-threshold region that is dominated by various 6s6p2 negative-ion resonances. © 2009 The American Physical Society URL:
