✦ Synopsis

Levels in 123 Te were investigated in the range up to 3 MeV excitation energy by (n, γ ) and (d, p) reactions. Over 120 levels and about 140 γ -transitions were established most of them for the first time. The states below 2 MeV with the most complete spectroscopic information were interpreted in terms of the Interacting Boson-Fermion Model (IBFM). Unified treatment of both positive-and negative-parity states is achieved with constant parameters of the boson-fermion interaction for the whole chain of Te isotopes. Excitation energies, electromagnetic transition rates, γ -branchings and spectroscopic factors are discussed in connection with their possible structure. A family of low-spin negative-parity states has been identified and understood within the IBFM framework, thus proving their antialigned origin.
