Using the He-He system as a reference, we solve the Schr\\\"odinger equation for a family of potentials having different values of the two-body scattering length $a$ and we compare our results to the universal zero-range form deduced by Efimov, $ak\\cot\\delta=c_1(ka)+c_2(ka)\\cot[s_0\\ln(\\kappa_*a)+\\phi(ka)]$, for selected values of the three-body parameter $\\kappa_*$.
