本文报道了中性汞在磁光阱中利用253.7nm处自旋禁戒1S0 → 3P1跃迁冷却的实验结果。我们捕获了两种汞同位素，即玻色子202汞和费米199汞同位素，分别。用改进的TOF方法测得冷原子云的温度约为300μK。它目前受到激光锁质量的限制。捕获的中性汞有许多有趣的途径，如时间标准和高精度测量。在这里，我们讨论了光缔合光谱和超冷Hg 2二聚体的产生的可能性。
We report on the cooling of neutral mercury in a magneto-optical trap utilizing the spin forbidden1S0→3P1transition at 253.7 nm. We trapped two Hg isotopes, i.e. the bosonic202Hg and the fermionic199Hg isotope, respectively. The temperature of the cold atom cloud was determined to be approximately 300μK using a modified TOF-method. It is currently limited by the quality of the laser lock. Trapped neutral Hg has many interesting avenues such as a time standard and high precision measurements. Here, we discuss the possibilities of photo-association spectroscopy and the generation of ultra-cold Hg2dimers.
