      abstract     = {The Lamb-shift polarimeter (LSP) is a useful detection
                      apparatus to verify nuclear spin polarizationfor atoms,
                      molecules and ions consisting of hydrogen and/or its
                      isotopes. Its functionality relieson the creation of
                      metastable hydrogen atoms via a charge exchange reaction
                      that preserves thenuclear polarization in a strong magnetic
                      field. The nuclear polarization is then determinedby
                      analyzing the relative occupation numbers between different
                      metastable hyperfine states withdifferent nuclear spin
                      projection 𝑚𝐼 . This makes the LSP a very rapid and
                      cost efficient detectionmethod for beams with a beam energy
                      in the keV range as no pre-acceleration is needed. In
                      thepast it was shown that many of the above mentioned
                      candidates like $𝐻^+$, $𝐷^+$, $𝐻𝐷$ etc. could
                      bemeasured with success, and in this work an additional ion,
                      i.e. $𝐻^−$ , adds up to the list. Furthermore,the
                      measurements of polarized $𝐻^−$ ions have been
                      performed for pulsed beams as it was in usefor long times at
                      the cooler synchrotron COSY in Jülich. In the second part,
                      a theoretical outlookfor possible adaptations to the spin
                      filter is given, which is an important component of the
                      LSP.This paves the way to realize experiments investigating
                      the bound beta decay or parity violation inmetastable
                      hydrogen atoms. In addition, a short outlook for possible
                      applications of $^3𝐻𝑒$ beamsis given.},
