While they zip around at relativistic speeds, gaining effective relativistic mass, the two outermost electron shells (also drawn in towards the heavy nucleus) are slightly closer to each other as ...

Feb 15, 2013: Black gold: enabling bright, high rep-rate electron beams (Nanowerk News) Free electron lasers (FELs) have proven their worth, but next-generation light sources will have to do better ...

Theirs was the first demonstration of relativistic electron beams from a nanostructured photocathode in a high-gradient ... Black gold: Enabling bright, high rep-rate electron beams (2013 ...

The unique properties of gold can be largely explained by Albert Einstein’s theory of relativity. Chemists from Heidelberg University have been able to demonstrate this through their ...
