N2 - We report on our Stochastic Variational Method (SVM) calculations of η-nuclear quasi-bound states in s-shell nuclei as well as the very recent calculation of the p-shell nucleus 6Li. The ηN potentials used were constructed from ηN scattering amplitudes obtained within coupled-channel models that incorporate N∗(1535) resonance. We found that η6Li is bound in the N interaction models that yield Rea 0:67 fm. Additional repulsion caused by the imaginary part of eta;N potentials shifts the onset of nuclear binding to 4He, yielding very likely no quasi-bound state in 3He.
