Calculations of eta-nuclear quasi-bound states in few-body systems

Original language description

We report on our Stochastic Variational Method (SVM) calculations of eta-nuclear quasi-bound states in s-shell nuclei as well as the very recent calculation of the p-shell nucleus Li-6. The eta N potentials used were constructed from eta N scattering amplitudes obtained within coupled-channel models that incorporate N*(1535) resonance. We found that eta Li-6 is bound in the eta N interaction models that yield Rea(eta N) >= 0.67 fm. Additional repulsion caused by the imaginary part of eta N potentials shifts the onset of eta-nuclear binding to eta He-4, yielding very likely no quasi-bound state in eta He-3.
