摘　　要：将近似角动量投影形变Hartree Fock(PDHF)方法用于 3s 2d 1g壳层区核的奇A核 ,实际计算了119I,12 1I和12 3 I 3个核的基态带和低激发态带的能谱 .按ΔI=2划分带结构 ,发现PDHF的计算结果与实验能级符合较好 .同时也用粒子加转子模型对能谱进行了分析讨论 。The approximate angular momentum projected deform Hartree Fock (PDHF) method is used to study some odd A nuclei in the 3s 2d 1g shell: 119 I, 121 I and 123 I. Their ground bands and low excited bands are calculated. The theoretical results with ΔI =2 band structure are fit well with the experimental data. Then the characteristics of the spectra are analyzed and discussed with the particle rotor model. It is explained that the PDHF spectra have the properties of the decoupled limit spectra.
