极化原子束有许多重要应用,如用来研究原子散射过程,制备极化核,研究表面特性,检验宇称不守恒,浓缩同位素等等.但是,现有的工作都局限于碱金属原子,而多电子原子极化束制备和应用研究尚未见报道.我们在Li和Rb原子束极化和同位素浓缩的基础上,最近用一台连续波染料激光抽运,制备出部分极化的稀土Eu原子束;利用其磁偏转效应,观察到Eu的两种同位素的浓缩效果. Polarized atomic beam has many important applications, such as the study of atomic scattering process, the preparation of polarized nuclei, the study of surface properties, test parity is not conserved, concentrated isotopes, etc. However, the existing work is limited to alkali metal atoms, However, the preparation and application of the multi-electron atomic polarization beam has not been reported yet.We recently laser-pumped with a continuous wave dye based on Li and Rb atomic beam polarization and isotope concentration to prepare a partially polarized rare earth Eu Atomic beam; the use of its magnetic deflection effect observed Eu two kinds of isotope concentration effect.
