【摘要】 本文对于Pt偶同位素中的h_9/2质子对的排列现象作了比较系统的计算和讨论。结果表明,如用改善的Nilsson参数κ、μ给出的πh_9/2的排列频率与Vi_13/2排列频率的差值△（?）w_C=（?）w_c(πh_9/2-hw_c(vi_13/2对于₇₈¹⁸⁴Pt₁₀₆核具有最小值,约为75keV。这和最近实验上确定的¹⁸⁴Pt核转晕带上出现的大的上弯现象,是由于vi_13/2和πh_9/2两个排列频率非常靠近的结果一致。而运用Nilsson的标准κ、μ则不能给出这一结果。这两个排列的先后次序仍是值得深入研究的问题。对于相邻Pt偶同位素的πh_9/2排列频率的理论预言,期待着实验数据的检验。更多还原

【Abstract】 πh_9/2 alignment in Pt even isotopes has been calculated and discussed systematically. It is found that △（?）w_c（?）（?）w_c(πh_9/2)-（?）w_c(vi_15/2) approches the minimum, about 75keV₁ for 1 ₇₈⁸⁴Pt₁₀₆ by using modified Nilsson’s parametersκμ. This result is in agreement with the experimental evidence that the big up-bend observed in the yeast band of ¹⁸⁴Pt is caused by the lose alignment of πh_9/2 and vi_13/2. While the standard Nilsson’s κμ can not give out such a result. The problem of the order of πh_9/2 and vi_13/2 alignments needs further investigation. The pretical prediction about the πh_9/2 alignment frequency for neighboring Pt even isotopes should be checked by new experiments.更多还原
