Abstract
Charmonium (cc̄) bound states in few-nucleon systems, 2H, 4He and 8Be, are studied via Gaussian Expansion Method (GEM). We adopt a Gaussian potential as an effective (cc̄)-nucleon (N) interaction. The relation between two-body (cc̄)-N scattering length acc̄-N and the binding energies B of (cc̄)-nucleus bound states are given. Recent lattice QCD data of acc̄-N corresponds to B ≃ 0.5 MeV for (cc̄)-4 He and 2 MeV for (cc̄)-8Be in our results.
