An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a ...

The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

The first direct observation of the orbital structure of an excited hydrogen atom, made using a newly developed "quantum microscope." (Stodolna et al. / Physical Review Letters) Image 2 of 2 ...

The team chose the hydrogen atom thanks to its unique properties. “These [hydrogen atoms] are very peculiar…as hydrogen has only one electron, which interacts with the nucleus via a purely Coulombic ...

The two collaborations combined their complementary data on the proton's inner structure to improve calculations of a ...
