We demonstrate that changing the reduced mass in scattering calculations is equivalent to changing the potential. We explore how small changes in the mass alter the scattering length of hydrogen atoms when they interact via the X¹Σ_g⁺ and b³Σ_u⁺ molecular states. We show how the variation of scattering length with mass depends on the asymptotic potential.
