AΛ^(*) 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.
