摘要:
基于前人核能测量数据,研究188Re经β-衰变到达188Os的各低激发态的能级值,及各能级间的跃迁γ分支比,各γ射线的跃迁能量和跃迁强度等.经分析筛选及用新标准重新归一,推荐最佳实验数据,对测量误差采用加权平均法确定;对没有新实验数据的,多采用Singnh B推荐数据;对衰变纲图及其衰变特性不完全自洽,推荐物理量不齐全的,用国际ENSDF评价系统,以原推荐最佳实验数据为基础进行自洽处理与理论计算.该理论计算填补了目前实验数据不足的空缺,给出了一个更合理的188Os能级结构纲图.
Abstract:
With the new 188Re decay data we studied the nuclear structure of 188Re and evaluated the nuclear experiment data which includes the level energies of 188Os from 188Re β- decay,and the ratios,energies and intensities of γ transitions. We compared and filtrated all the data and then proposed a group of new data.The deviations of the data were processed using the method of weighted mean. Finally we used the ENSDF system and Ge(Li) spectrometers to study the gamma singles and gamma-gamma coincidence spectra of 17.004 h 188Re beta decay and built up the new 188Re decay scheme. The consistence between the calculated and measured coincidence intensities was demonstrated.
