| Özet: | Title screen We discuss a possible interpretation of the f ₀(980)-meson as a hadronic molecule —a bound state of K and KK mesons. Using a phenomenological Lagrangian approach we calculate the strong f 0(980) -ππ and electromagnetic f₀(980) - үү decays. The compositeness condition provides a self-consistent method to determine the coupling constant between f₀ and its constituents, K and KK. Form factors governing the decays of the f 0(980) are calculated by evaluating the kaon loop integrals. The predicted f₀(980) - ππ and f₀(980) - γγ decay widths are in good agreement with available data and results of other theoretical approaches.
