Polarization-dependent disappearance of a resonance signal: Indication for optical pumping in a storage ring?

We report on laser spectroscopic measurements on Li^{+} ions in the experimental storage ring ESR at the GSI Helmholtz Centre for Heavy Ion Research. Driving the 2s ^{3}S_{1}(F=3/2)↔2p ^{3}P_{2}(F=5/2)↔2s ^{3}S_{1}(F=5/2) Λ-transition in ^{7}Li^{+} with two superimposed laser beams it was found that...
