Abstract

Antihydrogen production in amounts sufficient for two-photon spectroscopy of 1s-2s transition aimed at checking the hydrogen-antihydrogen symmetry is one of the most ambitious current projects.^1,2 One of the possible ways is to use positron-antiproton capture in traps when high-density clouds of accumulated antiprotons and positrons are brought and kept together by means of specially chosen electromagnetic field and strong cooling (was not demonstrated up to now).
