将角动量投影壳模型应用到84 Rb核 ,对组态为πg9 2 νg9 2 的正宇称晕带和组态为π(p3 2 ,f5 2 ) νg9 2 的负宇称晕带理论计算和实验结果进行了比较 ,特别是对正宇称晕带中的signature反转机理进行了探讨 .角动量投影壳模型计算显示正宇称晕带中的signature反转是原子核随自旋增加形状发生变化的信号 ,其间原子核从低自旋的长椭球通过三轴形变变到高自旋的扁椭球 .此外 ,还确定了此两带的原子核形状 .
The angular momentum projection shell model was applied to the 84 Rb kernel and the positive parity halo with πg9 2 νg9 2 and the negative-parity halo with π (p3 2, f5 2) νg9 2 were calculated and experimentally calculated And the signature inversion mechanism in the positive parity halo is discussed.The angular momentum projection shell model calculation shows that the signature inversion in the positive parity halo is the change of the nucleus with increasing spin shape Signal during which the nuclei change from a low-spheroid ellipsoid to a highly spheroid ellipsoid through triaxial deformation. In addition, the shape of the nuclei of these two bands is also determined.
