The odd-even nucleus 125Ce was studied via in-beam γ-ray spectroscopy using the 40Ca + 92Mo reaction at 190 MeV. Four rotational bands were observed, two of them being identified for the first time. New connecting transitions were identified between the bands, which leads to new spin assignment for one of the previously known bands. We propose J = 7/2- for the ground state of 125Ce. The bands are discussed in the framework of the IBFM + broken-pairs model.

Abstract
The odd-even nucleus 125Ce was studied via in-beam γ-ray spectroscopy using the 40Ca + 92Mo reaction at 190 MeV. Four rotational bands were observed, two of them being identified for the first time. New connecting transitions were identified between the bands, which leads to new spin assignment for one of the previously known bands. We propose J = 7/2- for the ground state of 125Ce. The bands are discussed in the framework of the IBFM + broken-pairs model.
