利用在束Y实验方法对~(117)Xe的激发态进行了延迟符合测量,从(117) ̄Xe的401keV(15/2-→11/2-)和205keV(7/2-→5/2+)两跃迁的延迟符合时间谱中,提取出T1/2=(59±20)ns和(16.5±8.0)ns两个半寿命,并将其分别指定给了11/2.7/2两个能级。关键词
The delayed coincidence measurements of the excited state of ~ (117) Xe were carried out using the experimental method in beam Y. From 401keV (15 / 2- → 11 / 2-) and 205keV (7 / 2- → 5 / 2+), the two half-lives of T1 / 2 = (59 ± 20) ns and (16.5 ± 8.0) ns are extracted and assigned to 11/2 respectively. 7/2 two levels. Key words
