Comment on: “Quantization of the highest levels in a molecular potential”

The correction to the JWKB quantization formula for molecular potentials can be understood as correction to the phase losses due to reflection at the turning points. For a potential with an attractive inverse power law tail an analytical formula can be derived for the correction, and the probability distribution of binding energies Eb near threshold is proportional to $E_{\rm b}^{-1/2}$ with known constant of proportionality
