Abstract. The influence of the interaction in the particle-particle channel on the properties of low-lying excited slates (2₁⁺, 2₂⁺, 4₁⁺, 4₂⁺) in some spherical nuclei (¹²²Te, ¹¹⁴Cd, ¹¹⁶Cd) is studied. The studies are carried out in the framework of the quasiparticle-phonon model. The results point out that the switching on of the in?teraction decreases the anharmonic quasiparticle-phonon matrix element and it increases the value of the two-phonon components in the structure of the wave function of 2₂⁺ and 4₁⁺ stales. It is in agreement with the experimental data. More adequate description of the properties of low-lying states could be reached by diagonalizing the Hamiltonian in a larger basis including three-phonon components.
