BUFFALO, N.Y. — You probably learned in high school chemistry class that core electrons don’t participate in chemical bonding. They’re thought to be too deep inside an atom and close to the nucleus to ...

A University at Buffalo study provides new insights about core electrons, including their role in the B1-B2 transition that sees a compound's atomic crystal structure rearrange from an octahedral ...

Auger decay is a fundamental non-radiative process that occurs following the creation of a core-hole state in an atom or molecule by high-energy photons. When a core electron is ejected during ...

Scientists use European XFEL's fast X-ray pulses for doubly resonant ionisation of krypton. (Nanowerk News) Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto ...

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a short-lived window of opportunity opens. For just a few femtoseconds, before an ...

The Electron Optics Facility (EOF) includes three scanning electron microscopes (SEM), an aberration-corrected atomic resolution scanning transmission electron microscope (STEM), and a focused ion ...
