In the chemistry of interstellar clouds, the three-atomic hydrogen ion plays a key role. In these reactions, also simple organic molecules form. Although H3+ is the simplest polyatomic molecular ion, ...
Red light stop: The experiment uses multiple frequencies of light to cool the CaOH atoms to a fraction of a degree above absolute zero. (Courtesy: John Doyle) Physicists in the US have created ...
Bombarding a material with an ion beam provides valuable information about its surface composition. Ion guns that fire polyatomic ions can reveal more detailed information and cause less damage to the ...
