Physicists create a new form of Hydrogen
21 January 2017 Current Affairs: 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.

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.

It will help researchers to easily identify the clusters in nature.
