Onset of η-nuclear binding

Research output: Contribution to journalArticlepeer-review


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 aηN ≈ 1 fm is needed to bind η 3He, whereas η 4He binding requires a minimum value Re aηN ≈ 0.7 fm.
