Weak atomic bond, theorized 14 years ago, observed for first time

03-Nov-2016

A Purdue University physicist has observed a butterfly Rydberg molecule, a weak pairing of two highly excitable atoms that he predicted would exist more than a decade ago. Rydberg molecules are formed when an electron is kicked far from an atom's nucleus. Chris Greene, Purdue's Albert Overhauser ...
