Investigation of the fine structure of Antihydrogen


19 Feb 2020

On February 19, 2020, ALPHA published the first investigation of the fine structure of Antihydrogen. These measurements of transitions in the 1S-2P manifold, in combination we previous detailed measurements of the 1S-2S transition has allowed us to determine the 2S1/2-2P1/2 splitting (the classic Lamb shift) in antihydrogen. The results appeared today in Nature.
