Compositeness of near-threshold states with repulsive Coulomb plus short-range forces can be written in terms of the Coulomb scattering length, effective range, and Bohr radius; shallow bound states and nearby resonances both tend to be composite-dominant.

Compositeness of near-threshold states with repulsive Coulomb interaction combined with short-range potential
Compositeness of near-threshold states with repulsive Coulomb plus short-range forces can be written in terms of the Coulomb scattering length, effective range, and Bohr radius; shallow bound states and nearby resonances both tend to be composite-dominant.
