WoodsSaxon potentials are utilized to predict the groundstate binding energies of all A = 2 − 6 Λ hypernuclei. In total, twenty hypernuclei are considered in this paper. The model is generally within 500 keV of the measured groundstate binding energy value in the                         3H, 4H, 4He, 5He and 6He systems. The best fit to the known A ≤ 6 Λ hypernuclei groundstate binding energies requires a potential form similar to the Rost interaction with the addition of a term dependent on the number of baryons in the system. The derived potentials are not unique and additional data are needed to further refine the Λnucleus potential in light hypernuclei.
