Physicists create a new form of Hydrogen

Physicists from Austria have created new form of Hydrogen i.e. negatively charged hydrogen clusters. It is a previously unseen form of hydrogen.

For the past forty years, existence of hydrogen in ion clusters was known and is positively-charged clusters have already exists.

How negatively charged Hydrogen Clusters were created?
  • Researchers first injected cold liquid helium droplets with hydrogen molecules to form clusters with a neutral charge. Then they exposed these hydrogen-infused droplets to an electron beam.
  • This caused some hydrogen molecules to ionize and be flung out into the surrounding vacuum as negatively charged hydrogen ions.
  • Soon, the nearby hydrogen molecules started clustering around the negatively charged ions to create negatively charged hydrogen clusters that could boast a few, or many molecules each.
  • The newly created negatively charged hydrogen clusters existed only for microseconds (1 microsecond = 0.000001 seconds). But it was enough time for researchers to determine their geometric structures.
  • Significance of Research: It will help researchers to easily identify the clusters in nature.
