摘要：
We present an exact procedure that allows one to calculate the scattering length for any potential expressed as an algebraic sum of inverse powers of the inter-atomic distance. We apply it to (12, s) Lennard-Jones potentials, with different values of s. The procedure is suitable for a very precise determination of the intensities of the potential corresponding to zeros or poles of the scattering length.
