Berkeley Team take first-ever measurements of Einsteinium
February 5th, 2021
“Structural and Spectroscopic Characterization of an Einsteinium Complex,” has been published in Nature; A study co-led by Berkeley Lab scientist and UC Berkeley Nuclear Engineering (UCBNE) Assistant Professor Rebecca Abergel, Los Alamos National Laboratory (LLNL) scientist Stosh Kozimor, and a team of scientists: study co-authors Korey Carter, Katherine Shield (current UCBNE Grad student), Kurt Smith, Leticia Arnedo-Sanchez, Tracy Mattox, Liane Moreau, and Corwin Booth of Berkeley Lab; Zachary Jones and Stosh Kozimor of Los Alamos National Laboratory; and Jennifer Wacker and Karah Knope of Georgetown University—several of whom are graduate students and postdoctoral fellows.
The research was supported by the DOE Office of Science. Luminescence spectroscopy experiments were conducted at the Molecular Foundry at Berkeley Lab, and X-ray absorption spectroscopy at the Stanford Synchrotron Radiation Lightsource (SSRL) at SLAC National Accelerator Laboratory. With experimental facilities not available in 1952, when Einsteinium was discovered, the team measured the first-ever Einsteinium bond distance and with less than 250 nanograms of the element!
“There’s not much known about einsteinium,” said Abergel, who leads Berkeley Lab’s Heavy Element Chemistry group. “It’s a remarkable achievement that we were able to work with this small amount of material and do inorganic chemistry. It’s significant because the more we understand about its chemical behavior, the more we can apply this understanding for the development of new materials or new technologies, not necessarily just with einsteinium, but with the rest of the actinides too. And we can establish trends in the periodic table.”
Congratulations Professor Abergel and Kathy Shield! —from your UCBNE family.
