The ALPHA-2 (Anti-Hydrogen Laser Physics Apparatus) experiment has made the first observations comparing the light emitted from hydrogen atoms made of antimatter to the light emitted from hydrogen ...

ALPHA published a paper in the journal Nature this week that reports the first ever measurement of the optical spectrum of an antimatter atom. The team behind the paper says that this is the result of ...

SINCE the negatively charged hydrogen atom is known to exist, from work on positive rays, it seemed likely that Silberstein's particular solution of the three-body problem, applied by him to the case ...

For the first time, and contrary to popular belief, scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it’s impossible to ...

What you’re looking at is the first direct observation of an atom’s electron orbital — an atom’s actual wave function! To capture the image, researchers utilized a new quantum microscope — an ...

Scientists have captured the first ever photo of an electron’s whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique. Seeing inside the tiniest bits of matter is a ...

Hydrogen’s antimatter counterpart has shown its true colours, and they are just what physicists ordered. Antihydrogen atoms are made of a positron (a positively charged version of the electron) ...

Infrared spectroscopy is a standard technique, which depends upon the interaction between infrared radiation and the vibrating dipole moments of molecules. Except for homonuclear diatomics and noble ...
