Evaporative Cooling of Anions
Physicists from Heidelberg and Innsbruck develop technique for cooling negatively charged molecules
Radio frequency trap, in which the negatively charged molecules are trapped and evaporated with light. | Molecular anions, negatively charged molecules, are difficult to cool due to their specific electronic configuration. A team of physicists led by Matthias Weidemüller from Heidelberg University’s Institute for Physics and Roland Wester from the Department of Ion Physics and Applied Physics at the University of Innsbruck (Austria) have now developed a new method for cooling molecular anions to below three Kelvin, i.e. approximately minus 270 degrees Celsius, in a short time. ...TO READ THIS ARTICLE, CREATE YOUR ACCOUNT
