Abstract
Relativistic configuration-interaction calculations have been performed for anion binding energies of the entire actinide row using a corelike treatment of the 5f subshell: the same occupancy and universal jls restrictions are applied to the subshell throughout the basis of each neutral and anion calculation. We predict bound 7p attachments to all actinide ground state configurations except Fm, Md, and No. Additional anion bound states are formed by 7p attachment to excited thresholds in Pa and Lr as well as 7s attachments relative to excited open- s thresholds in Th, Pa, U, and Np. Of the 41 bound actinide anion states presented, over half are characterized here for the first time. The most unusual case is Pa-, where these ab initio calculations predict five bound anion states arising from four different configurations. © 2009 The American Physical Society.
