Foundry users, working with staff, performed spectroscopic and structural characterization of an einsteinium coordination complex.
Significance and Impact
New strategies developed to work with minute sample sizes of Es-254 reveal an intermediate spin-orbit coupling scheme and open the door to studying the fundamental coordination properties of the transplutonium actinides.
- Element-specific characterization techniques, luminescence spectroscopy and X-ray absorption spectroscopy, were employed to characterize einsteinium (Es), using less than 200 ng of material.
- The energy of the L3 absorption edge and a bond distance for Es-254 were measured.
- Photophysical measurements revealed a hypsochromic shift upon metal complexation, opposite from what has been previously observed with other f-elements.
