Excited state G factors in ¹²⁵Te

The transient-field technique has been used to measure, with considerably improved precision, the g factors of the 3/2⁺ and 5/2⁺ states in ¹²⁵Te at 444 and 463 keV, respectively, relative to the g factor of the first excited state in ¹²⁶Te. Together with shell model and weak-coupling core-excitation model calculations, the g-factor measurements provide insight into the orbital occupation of the odd neutron for the low-excitation states in ¹²⁵Te. A new 9/2⁺ level at 1029 keV, together with a firm 7/2⁺ spin assignment for the level at 1018 keV, identifies candidate states for the coupling of the s neutron to the 4⁺ core excitation.
