O17和F17低能反宇称态的相干结构

应用壳模型方法计算了O¹⁷和F¹⁷的低能反宇称态。核子间剩余相互作用取为δ型核力。第一步在L-S耦合近似下求解方程。结果表明,低能态具有“配对”的相干结构。第二步用一种近似办法加进了自旋轨道耦合力,得到了可以和实验进行比较的能谱。计算了已有实验数据的跃迁几率。

THE LOW ENERGY OPPOSITE PARITY COHERENT STRUCTURE OF O17 AND F17

The low energy opposite parity states of O¹⁷ and F¹⁷ are calculated by using the shell model method. The residual interaction between nucleons is considered as the δ-type force. First, the equations are solved under the L-S coupling approximation, and the result reveals that the low energy states possess the "pairing" coherent structure. Next, the spin-orbit coupling force is introduced by a certain approximate method, and an energy spectrum comparable with experiment is obtained. The transition probabilities corresponding to the existing experimental data are also calculated.
