论文摘要
使用基于球形和变形的木材 - 撒克逊电位的知识的简单模型，这表明在$^{29} $ f中对光环现象的最新观察可以解释为$^{29} $ f的基态状态的证据。倾斜的变形是壳结构的结果，壳结构是独特的，它在一个独特的谐振水平上，尤其是中子1 $ f_ {7/2} $和2 $ p_ {3/2} $谐振水平的脱发，以及在Proton数字$ z $ = 9的强大偏好中，与Proton的强烈偏好相同。 $ z $ = 8可能的中子壳结构的存在可能不会使系统变形。因此，质子数字8和9分别强烈偏爱特定形状，以及中子$ 1D_ {3/2} $和$ 2S_ {1/2} $ orbits中的氧气同位素的$ 2S_ {1/2} $ orbits之间的能量差异似乎在氧气中的氧气中含氧化物的现象中起着重要作用。 1999。
Using a simple model based on the knowledge of spherical and deformed Woods-Saxon potentials, it is shown that the recent observation of halo phenomena in $^{29}$F can be interpreted as an evidence for the prolate deformation of the ground state of $^{29}$F. The prolate deformation is the result of the shell structure, which is unique in one-neutron resonant levels, in particular near degeneracy of the neutron 1$f_{7/2}$ and 2$p_{3/2}$ resonant levels, together with the strong preference of prolate shape by the proton number $Z$ = 9. On the other hand, in oxygen isotopes spherical shape is so much favored by the proton number $Z$ = 8 that the presence of possible neutron shell-structure may not make the system deformed. Thus, the strong preference of particular shape by the proton numbers 8 and 9, respectively, together with a considerable amount of the energy difference between the neutron $1d_{3/2}$ and $2s_{1/2}$ orbits in oxygen isotopes seems to play an important role in the phenomena of oxygen neutron drip line anomaly, as was suggested by H. Sakurai {\it et al.} in 1999.
