N1 - Funding Information:
We are grateful to P. Maier-Komor and to K. Nacke for the target preparation and to T. Faestermann for the Q3D maintenance. The technical staff of the reactor at l~e2 and of the accelerator laboratory in Munich deserve appreciation for providing us with excellent beams. One of us (V.B.) is grateful to the NPI, l~e~ and the TU, Munich for the hospitality extended. This work was supported by the Grant Agency of the Czech Republic (No. 202/97/K038), partly by the Volkswagen Foundation and by the Deutsche Forschungsgemeinschaft, Bonn (Eg 25/4, Gr 894/2).

N2 - Levels in 125Te were investigated in the range up to 3.3 MeV excitation energy by the (n,γ), (d,p) and (3He,α) reactions. Over 160 levels and about 360 γ-transitions were established, most for the first time. The states below 2.3 MeV with the most complete spectroscopic information were interpreted in terms of the interacting boson-fermion model (IBFM). Unitary treatment of both positive- and negative-parity states is achieved with the same model parameter close to the intermediate case between O(6) and U(5) limits. Excitation energies, electromagnetic transition rates, γ-branchings and spectroscopic factors are discussed in connection with the possible structures. A family of low-spin negative-parity states has been identified and understood by the IBFM proving their antialigned origin.
