The structure of low-lying levels in odd-mass Te isotopes (115≤A≤131) is discussed in the framework of the quasiparticle-phonon model. In addition, the properties of ${}_{}{}^{131}{}_{}{}^{}\mathrm{Te}$ are also investigated by means of three-particle cluster-phonon coupling, where the pairing force is taken as the residual particle-particle interaction. Excitation energies and spectroscopic factors are calculated and compared with the experimental data.
