Investigation of the fine structure of antihydrogen


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.
