摘　　要：By combining the Skyrme-Hartree-Fock method with complex momentum representation(CMR),the resonant states of_(Λ)^(17)O,_(Λ)^(41)Ca,_(Λ)^(49)Ca,and_(Λ)^(57)Ni were investigated.The phase shifts for hyperon-nucleus elastic scattering were determined with continuum level density(CLD),and the scattering length as well as the resonance energy were obtained by utilizing the effective range expansion.Our method,abbreviated as CMR-CLD,exhibits good consistency with traditional approaches and provides ground work for investigating scattering and resonance problems in deformed and multi-hyperon hypernuclei.
