We discuss the relation between the "compositeness" of an s-wave bound state, as derived from a related partial wave scattering amplitude, and the corresponding spatial probability densities, for the case of spherically symmetric, energy-independent finite-range potentials in non-relativistic quantum mechanics. We find that in this simple case "compositeness" is a measure for the probability to find the constituents separated by a distance greater than the interaction range.

A variation on "compositeness" (including higher partial waves)
For finite-range potentials, the compositeness of a bound state is exactly proportional to the probability of finding the particle outside a chosen radius, with a universal factor depending on angular momentum.

Single- and double-heavy Hadronic Molecules
A conference review argues that the X(3872), Tcc(3875), and the lowest open-charm states are hadronic molecules, and predicts an isovector partner Wc1 that should show up in B0 -> K0 J/psi pi pi decays.
