本文用γ射线谱方法重新研究了Kr核，用γ射线谱仪Ge阵列测量了Cf自发裂变后的γ射线。以前报告的一些过渡的顺序已经改变，并引入了新的水平。角相关分析允许分配的自旋几个级别在氪。这些数据与壳模型计算一起解释了Kr的近轴结构，它与Sr和Zr同位素的结构相似。三种同位素的规则系统学表明，Se同位素2073.4-keV能级的自旋与以前报道的值不同。利用Cm自发裂变的瞬发射线测量数据，我们重新研究了Se核。提出了一个新的六能级inSe的候选者，并得到了壳模型计算的支持.用一种新的系统学方法预测了Zn核2和4能级的能量。
TheKr nucleus has been reinvestigated with prompt--ray-spectroscopy methods using the Gammasphere Ge array to measurerays following spontaneous fission ofCf. The order of some of the transitions, reported previously, has been changed and new levels were introduced. Angular correlation analysis allowed the assignment of spins to several levels inKr. These data, together with the shell-model calculations, explained the near-yrast structure ofKr, which is similar to the structure of the,Sr, andZr isotones. The regular systematics obtained for the three isotones suggests that the spin of the 2073.4-keV level in theSe isotone is different from thevalue reported previously. Using data from prompt-ray measurement of spontaneous fission ofCm, we reinvestigated theSe nucleus. A new candidate for the 6level inSe has been proposed, which is supported by shell-model calculations. Energies of the 2and 4levels in theZn nucleus have been predicted using a novel systematics.
