| 英文摘要 | The 7Li＋ ion is one of the most important candidates for verifying QED theory and obtaining the precise value of the fine-structure constant ~. However, direct laser cooling of trapped Li＋ ions will lead to strong background fluorescence which will influence the spectrum detection. The sympathetic cooling technique is a good choice to solve the problem. In this work, we report sympathetic cooling of 7 Li＋ ions to few mK using 40Ca＋ ions in a linear Paul trap. A mixed ion crystal of 40Ca＋ ions and 7Li＋ ions are obtained. We also analyze the motion frequency spectra of pure 40 Ca＋ ions and mixed ions. |
