Rubidium Energy Levels (IMAGE) Chicago Quantum Exchange Caption A diagram of the electron energy levels of Rubidium. Two of the energy level gaps match the frequencies of optical photons and microwave ...

In a discovery that brings a legendary quantum theory to life, physicists at Princeton University have directly observed Hofstadter’s butterfly — a fractal pattern in electron energy levels that was ...

Electron energy loss spectroscopy (EELS) combined with advanced microscopy techniques has emerged as a formidable tool for exploring the intrinsic properties of materials at the nanometre scale. By ...

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 ...

Physicists in Germany have carried out the most accurate measurement to date of the width of the proton. By examining a previously unexplored energy-level transition in the hydrogen atom, Lothar ...

TEM works by transmitting a beam of electrons through an ultra-thin specimen. As the electrons interact with the specimen, they are scattered or transmitted, producing an image that is magnified and ...
