Abstract：
A chiral quark-model approach is extended to the study of the KN scattering at low energies. The process of K－p→Σ⁰π⁰ at P_K\≤800 MeV/c (i.e. the center mass energy W≤1.7 GeV) is investigated. The Λ(1405)S₀₁ dominates the reactions over the energy region considered here. Around P_K=400 MeV/c, the Λ(1520)D₀₃ is responsible for a strong resonant peak in the cross section. Our analysis suggests that there exist configuration mixings within the Λ(1405)S₀₁ and Λ(1670)S₀₁ as admixtures of the [70,²1,1/2] and [70,²8,1/2] configurations. The Λ(1405)S₀₁ is dominated by [70,²1,1/2], and Λ(1670)S₀₁ by [70,²8,1/2]. The non-resonant background contributions, i.e. u-channel and $t$-channel, also play important roles in the explanation of the angular distributions due to amplitude interferences.
