Bestimmung der Kerndipolmomente von171Yb und173Yb durch optisches Pumpen

The nuclear Zeeman levels of the odd isotopes of Ytterbium (171Yb,171 I=1/2;173Yb,173 I=5/2) were polarized in the atomic ground state (6s 2 1 S 0) by means of optical pumping with the resonance line (6s 2 1 S 0 ↔ 6s6p 1 P 1,λ=3988 a). The magnetic moments, calculated from the nuclear Hf-Zeeman transitions in a magnetic field of 228 Gauss are171 Μ I=0.49188 (2)Μ K 173 Μ I=0,67755 (3)Μ K (with diamagnetic correction applied).
