Abstract A Λ* resonance model for the η – Λ interaction near threshold is proposed. By assuming the Λ* (1670) excitation dominates in the K-p→ηΛ reaction near threshold, the corresponding η production cross section and the s-wave η - Λ scattering length are calculated. The obtained production cross section is consistent with the available experimental data, which indicates that the Λ* (1670) excitation is dominant in the production reaction near threshold. The η - Λ interaction is found to be attractive.
