Abstract :
The properties of the special levels in 124Te that are strongly populated by thermal neutron-capture γ-rays have been determined with 123Te(n,γ) and 124Te(γ,γ′) experiments. The unusual decay pattern can be consistently explained within the quasiparticle-phonon model assuming a three-phonon |21+ ⊗ 21+ ⊗ 31−; 2−〉 configuration of the upper intermediate level at 3.101 MeV which exclusively decays to a close-lying two-phonon |21+ ⊗ 31f-; 1f-f> state at 2.747 MeV. The (γ,γfʹ) reaction strongly excites the latter and also indicates the 1f- member of the three-phonon 21+ ⊗ 21+ ⊗ 31f- septuplet at 3.091 MeV.
