$^{107}$ In中的高自旋侵入带
High-spin intruder band in $^{107}$In
摘要:
利用$^{58}$ Ni($^{52}$ Cr,3 p)反应研究了缺中子核$^{107}$ In的高自旋态.使用JUROGAM检测器阵列测量束内$γ$射线。在2.002 MeV处观察到由10个$γ$射线跃迁组成的旋转级联,衰变到19/2 $^{+}$能级.该谱带具有光滑终止带的典型特征,而光滑终止带也出现在A $\sim$ 100区重核的转动谱带中。计算结果与全Routhian曲面和Cranked Nilsson-Strutinsky计算结果进行了比较。
英文摘要:
High-spin states in the neutron deficient nucleus $^{107}$In were studied via the $^{58}$Ni($^{52}$Cr, 3p) reaction. In-beam $γ$ rays were measured using the JUROGAM detector array. A rotational cascade consisting of ten $γ$-ray transitions which decays to the 19/2$^{+}$ level at 2.002 MeV was observed. The band exhibits the features typical for smooth terminating bands which also appear in rotational bands of heavier nuclei in the A$\sim$100 region. The results are compared with Total Routhian Surface and Cranked Nilsson-Strutinsky calculations.
