Abstract：
In this paper,a microscopic theory describing the intruder states in even-even nuclei near closed shells is appiled to calculate the low-lying spectrum and wavefunctions corresponding to ¹¹⁰Cd configurations.The affects of several factors on the formation of intruder states,the mechanism and the strength of configuration mixing are studied systematically.By comparison with phenomenological works,the s-d hamiltonian derived from the microscopic theory is investigated.
