Scientific paper

A set of 16544 A^{1}Σ_u^+ - X^{1}Σ_g^+ fluorescence line positions with a measurement precision of 0.001 cm^{-1}, and which samples ground state levels up to \upsilon^'' = 135 lying about 28 cm^{-1} below the dissociation limit, has been employed in least-squares fits using the MLR direct potential fitting approach. As well as the extended MLR model employed recently for Li_2, a further extension employing three y_i-variables leads to an optimum model for Cs_2 that ensures a realistic extrapolation into the long-range region in accord with the theoretical dispersion constants.
