摘要: AEgIS (Antimatter experiment: gravity, interferometry, spectroscopy) is an experiment approved by CERN with the goal of studying antihydrogen physics. In AEgIS, will be produced charge exchange reactions cold antiprotons positronium atoms excited in a Rydberg state (n > 20). first phase experiment, controlled acceleration electric field gradient (Stark effect) and subsequent measurement free fall Moire deflectometer allow test weak equivalence principle. second phase, slowed, confined, laser-cooled to perform CPT studies detailed spectroscopy. present work, after general description status advancement reviewed, special attention production excitation atoms.
