image: An image of the apparatus used to conduct the experiment, the MOTion trap, which is a system that allows neutral atoms and charged ions to be overlapped at temperatures near absolute zero. Laser light which is used to cool atoms in the experiment is visible inside of the apparatus. This material relates to a paper that appeared in the Sept. 7, 2017, online issue of Science, published by AAAS. The paper, by P. Puri at University of California, Los Angeles in Los Angeles, Calif., and colleagues was titled, "Synthesis of mixed hypermetallic oxide BaOCa+ from laser-cooled reagents in an atom-ion hybrid trap." view more
