| Abstract | Relativistic configuration-interaction calculations have been performed for anion states representing 6p attachments to 4f5d6s states in Gd and Tb as well as 6s attachments to 4f5d6s thresholds in Pr and Gd. The 4f subshell was treated as core-like with the same occupancy in all correlation configurations, and recently developed methods for reducing the complexity of the 4f subgroup were also employed. Results predict a single weakly bound (24 meV) even state for Pr−, twelve even states and three odd states for Gd− (the lowest level having an electron affinity of 234 meV), and six odd states for Tb−. The lowest 4f5d6s6p Tb− state is bound relative to the neutral 4f6s ground state by 88 meV, indicating that the Tb− ground state may actually be an attachment to the first excited state of the neutral atom. Revised calculations and analyses of the much simpler Lu−, La−, and Ce− anions are also presented. |
