Keywords: It's Electrifying JILA Scientists Use Electric Fields to Control Chemical Reactions of Ultracold Molecules (5940479983).jpg Schematic depiction of an energy barrier between polar molecules in an ultracold gas The fully symmetrical barrier left arises only between molecules known as fermions which if identical cannot occupy the same place at the same time This barrier greatly reduces the likelihood of chemical reactions When an electric field is applied to the gas the barrier is modified right so its height varies by direction Molecules that approach each other parallel to the electric field face a lower barrier and are more likely to react If molecules approach each other perpendicular to the electric field then the barrier is raised Credit Brian Neyenhuis/JILA Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5940479983/ It's Electrifying JILA Scientists Use Electric Fields to Control Chemical Reactions of Ultracold Molecules 2010-04-28 10 56 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5940479983 2016-09-07 02 34 06 United States Government Work Uncategorized 2016 November 4
