Precision Spectroscopy of Hydrogen with aLamb-Shift Polarimeter

摘要

A spinfilter, the most important component of a Lamb-shift polarimeter, is used to produce a beam of metastable hydrogen (deuterium) atoms in one hyperfine state (HFS)(α1, α2 and together with the Sona transition β_3). As function of a magnetic field separated transitions between the 2S_(1/2) metastable Zeeman states seem to be observable as well as single transitions into the short-lived 2P_(1/2) and 2P_(3/2) states. The Breit-Rabi diagrams for these states and, therefore, the g factors can be measured with good precision. Furthermore, the hyperfine splittings and the Lamb shift can be observed as well. Application of this method to anti-hydrogen atoms is suggested.
