论文摘要
使用评估的核结构数据文件（ENSDF）在整个核图表上审查了均匀核的自旋和平等（$ j^π$）。确认了2 $^+_ 1 $的流行率。使用ENSDF数据评估程序重新检查0 $^+_ 2 $，2 $，1 $^-_ 1 $的属性。讨论了$ j^π$系统的趋势和水平量子数与核物理现象之间的相关性。
The spin and parity ($J^π$) assignments in even-even nuclei were reviewed across the nuclear chart using the Evaluated Nuclear Structure Data File (ENSDF). The prevalence of 2$^+_1$ first or lowest excited states is confirmed. The properties of 0$^+_2$, 1$^-_1$, and 3$^-_1$ lowest excited states were reexamined using the ENSDF data evaluation procedures. The $J^π$ systematic trends and correlations between level quantum numbers and nuclear physics phenomena are discussed.
