Abstract.

The low-lying level structure of atomic lawrencium has been calculated by using medium- to large-scale multiconfiguration Dirac-Fock wave functions. From these computations, an overview on the excitation energies and absorption rates is compiled for the 30 lowest levels of the neutral atom with regard to its 7s2 7p 2P1/2 ○ ground state. For many of these levels, an accuracy of ∼1200 cm-1 is estimated by performing analogue computations for the homologous element lutetium. From the predicted level scheme, the excitation energies of about 15 levels fall into the spectroscopically relevant region between 20 000 and 30 000 cm-1 and, hence, might help in the set-up and interpretation of forthcoming experiments on the resonant excitation of atomic Lr.
