摘　　要：本文应用一种描述近满壳偶偶核的闯入态的微观理论,计算了对应于^(110)Cd组态的低能谱及波函数。系统地考察了各种因素对闯入态形成的影响、产生组态混合的机制及强度。通过与唯象工作的比较,考察了微观s-d哈密顿量。In this paper, a microscopic theory describing the intruder states in even-even nuclei near closed shells is applied to calculate the low-lying spectrum and wavefunctions corresponding to ^(110)Cd 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.
