N2 - The relations between two-body charmonium(cc)-nucleon(N) scattering length a and the binding energies of (cc) bound states in few-nucleon systems are studied. We adopt a Gaussian potential as an effective (cc)-N interaction. The results show that a ≤-0:95 fm is needed to form a (cc)-deuteron bound state. Also, a (cc)-4He and a (cc)-8Be bound states exist for a ≤-0:24 fm and α ≤-0:16 fm, respectively. Comparing our results with the recent lattice QCD data of α, we see that (cc)-nucleus bound states may exist for the nuclei with A ≥ 4.
