Abstract
The near-edge X-ray absorption fine structure at the L3 threshold is studied for compounds of U, Np-237, and Pu-239. The spectra exhibit single-peaked white lines at threshold, which shift by up to 6 eV to lower energies in the monochalcogenides and -pnictides relative to the tetravalent dioxides. These shifts systematically increase from U to Np and Pu as well as with increasing metalloid atomic number, reflecting increasing localization and occupancy of the 5f states.

For metallic systems, the L shift between trivalent and divalent Np is estimated to be 3.5 eV; it should be somewhat larger for the present case: B. Johansson, private communication (1987).
