Abstract
We report on the precise measurement of the atomic mass of a single proton with a purpose-built Penning-trap system. With a precision of 32 parts per trillion our result not only improves on the current CODATA literature value by a factor of 3, but also disagrees with it at a level of about 3 standard deviations.Year: 2017 PMID： 28777624 DOI： 10.1103/PhysRevLett.119.033001
