摘要
研究了奇质子核Lu和Ta同位素链h11/2质子9/2[514]转动带旋称劈裂的系统规律,并与同一核区奇奇核的πh11/2νi13/2两准粒子转动带低自旋区旋称劈裂规律进行了比较,指出奇质子Lu和Ta核三准粒子带的旋称反转很可能是来源于h11/2准质子和i13/2准中子之间的相互作用。
The systematic features of signature splitting of the h11/2 9/2 [ 514] rotational band in Lutetium and Tantalum isotope chains have been investigated and compared with that of πh11/2×vi13/2 2-quasiparticle band in oddodd nuclei of the same nuclear region. It is shown that signature inversion of 3-quasiparticle band of some odd- Z Lutetium and Tantalum nuclei most probably caused by the p-n interaction of h11/2 quasiproton and i13/2 quasineutron.
