(Phys.org) —Russian physicists Alex Gurevich and Anatoly Karashtin claim, in a paper published in the journal Physical Review Letters, they have found more evidence to support their idea that ...

Recent advances in electron density analysis and X‐ray diffraction studies have dramatically refined our understanding of atomic and molecular structures. By employing cutting‐edge techniques that ...

These images show the distribution of the valence electrons in the samples explored by the Brookhaven Lab collaboration -- both feature a central iron layer sandwiched between arsenic atoms. The tiny ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...
