Ba原子6sns(J=0,1)Rydberg系列

Spectroscopic properties of Ba 6sns(J=0,1) Rydberg series

采用三步共振激发方式 ,通过探测自电离过程产生的离子 ,在 ππ偏振组合方式和 πσ偏振组合方式下分别测得了 Ba原子 6sns1 S0 和 6sns3S1 Rydberg系列的能级位置 ,所得结果与理论和文献进行了比较和分析 ,结果符合得很好 .

A three step excitation scheme with different polarization configurations has been adopted to measure energy levels of Ba 6sns \+1S\-0 and 6sns \+3 S\-1 series by detecting ions originated from process.The experimental results agree well with the theory.
