Kapton中产生的低Z K原子的X射线跃迁产额
X-ray transition yields of low-Z kaonic atoms produced in Kapton
摘要:
在SIDDHARTA实验中首次测量了Kapton聚酰亚胺(C_(22)H_(10)N_2 O_5)中K原子的X射线跃迁产额。测定了低原子序数(Z = 6,7和8)和高主量子数(n = 5-8)的K原子的X射线产额。还测定了连续转变的相对产率比以及碳-氮(C:N)和碳-氧(C:O)的相对产率比。这些X射线产额为理解复合材料(如Kapton)中产生的K原子的俘获率和级联机制提供了重要信息。
英文摘要:
The X-ray transition yields of kaonic atoms produced in Kapton polyimide (C22H10N2O5) were measured for the first time in the SIDDHARTA experiment. X-ray yields of the kaonic atoms with low atomic numbers (Z = 6, 7, and 8) and transitions with high principal quantum numbers (n = 5-8) were determined. The relative yield ratios of the successive transitions and those of carbon-to-nitrogen (C:N) and carbon-to-oxygen (C:O) were also determined. These X-ray yields provide important information for understanding the capture ratios and cascade mechanisms of kaonic atoms produced in a compound material, such as Kapton.
