Hydrogen–anti-hydrogen scattering has been studied at low energies using quantal method. We employ the close-coupling method using different atomic basis sets. The same method has also been used to investigate hydrogen-hydrogen scattering. s-wave phase shifts and integrated elastic cross-sections are reported for both the systems. There is a structure in the elastic cross-section for hydrogen-hydrogen scattering.
