Abstract

Recent η few-nucleon stochastic variational method calculations that study the onset of η-nuclear binding are reviewed. The energy dependence of the ηN subthreshold interaction is treated self-consistently. These calculations suggest that a minimum value Re a_ηN ≈ 1 fm is needed to bind η ³He, whereas η ⁴He binding requires a minimum value Re a_ηN ≈ 0.7 fm.
