| Outline of Final Research Achievements |
The compositeness was studied to distinguish the molecular structure of hadrons among other exotic structure. The theoretical framework of the compositeness was reinforced, and it was found that to extract the wave function from the scattering amplitude, which is the solution of the Lippmann-Schwinger equation, has an advantage. In addition, the compositeness was evaluated from experimental data for the hadronic molecule candidates such as Δ(1232), N(1535), N(1650), a0(980), f0(980), and Ξ(1690).
