“Structural and Spectroscopic Characterization of an Einsteinium Complex,”
discovered in 1952 in the debris of the first hydrogen bomb
difficult to create and is highly radioactive.
The team of scientists had worked with einsteinium-254. It is one of the more stable isotopes of the element. It has a half-life of 276 days is known.
were able to examine this element using an accurate X-ray produced by a particle accelerator
