Why does changing just one proton in the nucleus of an atom create a different element? The number of protons in an atomic ...

On the move: time sequence of the electron distribution of the molecule 1,3-cyclohexadiene after it is excited by a light pulse. (Courtesy: SLAC) Scientists in the US and UK are the first to observe ...

I HAVE to thank the Editor for his kindness in allowing me to see Mr. Compton's letter. I believe Mr. Compton is right in ascribing the rapid decline in the intensities of the X-ray spectra as we ...

The Royal Society is a self-governing Fellowship of many of the world's most distinguished scientists drawn from all areas of science, engineering and medicine, and is the oldest scientific academy in ...

Often depicted as colorful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of ...

Researchers have measured how electrons in so-called transition metals get redistributed within a fraction of an optical oscillation cycle. They observed the electrons getting concentrated around the ...

This is a preview. Log in through your library . Abstract The behaviour of free electrons in ionic crystals in the presence of an external field is studied. It is shown that the usual method of ...

A valence electron in titanium oxide has been imaged at a resolution of 0.2 Angstroms using synchrotron X-ray diffraction and a new Fourier synthesis method that can determine the orbital states in ...
