介绍了Cs原子无自旋交换弛豫磁力仪(Cs-SERFM)的工作原理;分析了Cs泡温度105℃条件下,缓冲气体He的压强对Cs原子横向弛豫及线宽的影响,给出了惰性气体He的最佳压强为350×133.3 Pa;讨论了共振谱线的宽度与温度之间的关系,在105℃时Cs-SERFM谱线宽度仅为3.7 Hz。
The working principle of Cs-SERFM was introduced. The effect of pressure of buffer gas He on the transverse relaxation and linewidth of Cs atom was analyzed at Cs temperature of 105 ℃. The optimum pressure of inert gas He is 350 × 133.3 Pa. The relationship between the width of resonance line and temperature is discussed. The Cs-SERFM line width is only 3.7 Hz at 105 ℃.
