“…For the RKR potential we use a dissociation energy D e = 424(5) cm −1 (1 cm −1 = 29.9792458 GHz), defined as the energy difference between the bottom of the potential and the asymptotic energy. Reference [18] did not provide a tabulated IPA potential but expressed the potential in terms of Dunham coefficients Y lm . We have constructed a potential from the Y lm for l = 0-3, m = 0-5 provided in Table IV of Ref.…”

“…For the IPA potential we take the dissociation energy D e to be 431.0(1.0) cm −1 in accordance with fit of Ref. [18] to the last outer turning points of the potential. The 1.0 cm −1 uncertainty is based on the sensitivity of the fit with the order of the long-range dispersion expansion.…”

We have constructed the X 1 Σ + g potential for the collision between two ground state Mg atoms and analyzed the effect of uncertainties in the shape of the potential on scattering properties at ultra-cold temperatures. This potential reproduces the experimental term values to 0.2 cm −1 and has a scattering length of +1.4(5) nm where the error is prodominantly due to the uncertainty in the dissociation energy and the C 6 dispersion coefficient. A positive sign of the scattering length suggests that a Bose-Einstein condensate of ground state Mg atoms is stable.
