Figure 2

The ground-state energy of the relative motion Hamiltonian (5b) in the subspaces of given relative angular momentum \(\ell =0,\ldots ,4\) (labels on solid lines) for different values of the potential range a. Solid lines are obtained for simplified potential V while red dots for realistic interaction potential \({{V}}_{{ {\mathcal R} }}\) with Rc = 3a/π. It is clearly seen that for ranges smaller than the natural length of the harmonic oscillator (\(a\,\lessapprox \,1\)) both approaches give very similar results in a wide range of interaction strengths.
