摘要:

在一个$1s$原子电子被一个$K^{-}$取代的奇异原子中,$K^{-}$和原子核之间的强相互作用引入了能量移动和仅由电磁相互作用决定的低K原子能级的加宽。通过对Z= 1,2的K介子原子进行X射线光谱分析,SIDDHARTA实验高精度地确定了$K^{-}p$的$1s$态以及K介子氦-3和K介子氦-4的$2p$态的位移和宽度。这些结果提供了低能区K介子-核相互作用的独特信息。

英文摘要:

In the exotic atoms where one atomic $1s$ electron is replaced by a $K^{-}$, the strong interaction between the $K^{-}$ and the nucleus introduces an energy shift and broadening of the low-lying kaonic atomic levels which are determined by only the electromagnetic interaction. By performing X-ray spectroscopy for Z=1,2 kaonic atoms, the SIDDHARTA experiment determined with high precision the shift and width for the $1s$ state of $K^{-}p$ and the $2p$ state of kaonic helium-3 and kaonic helium-4. These results provided unique information of the kaon-nucleus interaction in the low energy limit.
