论文摘要
基于$^{120} $ I中报告的积极双重频段，已经讨论了包括旋转对齐在内的相应实验特性，并重新检查了相应的配置分配。自一致的倾斜轴振动相对论平均值计算表明，此双重频带是建立在配置上的$πh_{11/2} \ otimes的νH ^{ - 1} _ {11/2} $。此外，采用两个准粒子，再加上三轴转子模型，激发能，设备的努力参数$ s（i）$，$ b（m1）/b（e2）$，有效角度和$ k $ $ plots $与可用数据进行了讨论，并与可用数据进行了比较。所有这些结果都支持在$^{120} $ I中为正差双线带手性双重乐队的解释，因此确定了该核为$ a \ a \ of the the $ a \ 130 $岛的边界。
Based on the reported positive-parity doublet bands in $^{120}$I, the corresponding experimental characteristics including rotational alignment have been discussed and corresponding configuration assignment is reexamined. The self-consistent tilted axis cranking relativistic mean-field calculations indicates that this doublet bands is built on configuration $πh_{11/2}\otimes νh ^{-1}_{11/2}$. In addition, adopting the two quasiparticles coupled with a triaxial rotor model, the excitation energies, energy staggering parameter $S(I)$, $B(M1)/B(E2)$, effective angles, and $K$ $plots$ have been discussed and also compared with the available data. All of these results support the interpretation of chiral doublet bands for the positive-parity doublet bands in $^{120}$I, and hence identify this nucleus as the border of the $A \approx 130$ island of chiral candidates.
