Abstract
We have constructed the $XA I \Sigma_g^+ $ potential for the collision between two ground state Mg atoms andanalyzed 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$^{-l }$ and has a scattering length of +1.4(5) nmwhere the error is predominantly due to the uncertainty in the dissociation energy and the $C_6$ dispersioncoefficient. A positive sign of the scattering length suggests that a Bose-Einstein condensate of ground state Mgatoms is stable.Citation
