We critically review the LL dynamics by examining several LL and La phenomenological potentials in the study of the bound state properties of _LL  ⁶He, as a three-body system. The hyperspherical harmonics expansion method, which is an essentially exact method, has been employed for the three-body system. A convergence in binding energy up to 0.07% for K_max = 20 has been achieved. In our calculation, we made no approximation in restricting the allowed l-values of the interacting pair.
