【 摘 要 】

We present a systematic study for Coulombic three-body systems in very low-energy regime with mass ratio varying over several orders of magnitudes. Accurate phase shifts and scattering lengths are obtained by the Hyperspherical elliptic coordinate method. We identify the mass ratio dependence of the scattering lengths.
