The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This phenomenon is ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light ...

By 1970 interest in photoelectron spectroscopy was growing worldwide not only because of Kai Siegbahn’s work in the X-ray region, but also because of D.W. Turner’s work on UV photoelectron ...

This NASA Hubble Space Telescope image shows the planet Jupiter in a color composite of ultraviolet wavelengths. Released on Nov. 3, 2023, in honor of Jupiter reaching opposition, which occurs ...
