Abstract: An extension of the time-integrated atomic decoupling technique to measure g-factors of (sub)nanosecond isomers and/or the magnetic hyperfine field induced by highly excited atomic electrons on nuclei recoiling into vacuum is discussed. A high average field B-hf = 1080 (+270)(-175) T and an average atomic spin J = 2.7(2) is deduced using the known magnetic moment of a 4.05(7) mus isomer in Ge-69. Such high magnetic fields allow y-factor measurements of (sub)nanosecond states. Ab initio calculations show that the combination of a high average magnetic hyperfine: field and a high average atomic spin is only possible if a considerable fraction of the ions is ill a metastable excited state.
