Abstract
A new approach is discussed on how to obtain information on the compositeness of molecular states from combined information of the scattering length of the hadronic components, the effective range, and the binding energy, in which the range of the interaction is considered explicitly. This approach can improve the original formula of Weinberg, which was just obtained only in the limit of very small binding and zero range interaction. An application to three different cases, deuteron, D∗s0(2317) and D∗s1(2460), has been analyzed. The results show that we can determine simultaneously the value of the compositeness within a certain range, as well as get qualitative information on the range of the interaction.
