Abstract
In an atomic beam magnetic resonance experiment on Tb159 ΔF=0 transitions in several hfs-levels of thermally excited fine structure states have been observed. Detailed analysis of data showed twoJ=15/2 states, oneJ=13/2, oneJ=11/2, and, probably, oneJ=9/2 state to be present. For these levelsg J-values are given. It was concluded that the ground state of neutral terbium is 4f 8 5d 6s 2 8 G 15/2. The 4f 9 6s 2 6 H 15/2-level lies not more than 1000 cm−1 higher.
