摘要:

FINUDA实验收集了数据,以研究不同核靶上超核的产生。超核的形成通过奇异交换反应$K^-_{stop} + \; ^AZ \rightarrow \; ^A_ΛZ + π^-$进行。通过对$π^-$的动量分析,计算了$^7_Λ$ Li、$^9_Λ$ Be、$^{13}_Λ$ C和$^{16}_Λ$ O的结合能和形成几率。本文还讨论了形成几率随原子质量数A的变化规律。

英文摘要:

The FINUDA experiment collected data to study the production of hypernuclei on different nuclear targets. The hypernucleus formation occurred through the strangeness-exchange reaction $K^-_{stop} + \; ^AZ \rightarrow \; ^A_ΛZ + π^-$. From the analysis of the momentum of the emerging $π^-$, binding energies and formation probabilities of $^7_Λ$Li, $^9_Λ$Be, $^{13}_Λ$C and $^{16}_Λ$O have been measured and are here presented. The behavior of the formation probability as a function of the atomic mass number A is also discussed.
