Abstract: The two-center Coulomb scattering problem is revisited. It is shown that the scattering wavefunction can be interpreted in terms of distorted single-center Coulomb scattering solutions. The two-center properties are shown to manifest themselves merely in a non-integer quasi-angular momentum and an infinite series of short-range potentials decaying faster than r - 2 . Employing this distorted-wave ansatz, two-center Coulomb scattering phase shifts are determined numerically at the challenging low-energy regime with unprecedented accuracy. [ABSTRACT FROM AUTHOR]
