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 ⁺ ⊗ 3₁ ^f-; 1^f-f> state at 2.747 MeV. The (γ,γf') reaction strongly excites the latter and also indicates the 1^f- member of the three-phonon 2₁ ⁺ ⊗ 2₁ ⁺ ⊗ 3₁ ^f- septuplet at 3.091 MeV.
