摘要
A new experiment, by CERN's ATRAP collaboration, which introduced a technique for determining the quantum state in which antihydrogen atoms are formed was discussed. To make antihydrogen, antiprotons were taken from CERN's Antiproton Decelerator, further slowed down, and trapped with a configuration of electric fields. The evidence gathered confirmed that the H¯ atoms formed in the experiment occupy highly excited Rydberg states.
