Na原子斯塔克态寿命的实验测定
Lifetime Measurement of Stark States of Sodium
摘要
在1250~2000 V/cm的静电场变化范围内,用可调谐激光两步激发实现Na原子在n=17, m=0斯塔克簇各能态布居。采用延迟脉冲场电离方法测量了各斯塔克能态在不同外电场下的寿命。讨论了外电场强度和环境黑体辐射对斯塔克态寿命的影响。
Abstract
We have obtained the population of n=17, m=0 Stark states of sodium atom in the static electric fields ranged from 1250 to 2000 V/cm by two step excitation with tunable lasers. The lifetimes of the Stark manifold states are measured by using delayed electric field ionization. The influences of applied fields and blackbody radiation on the determination of the lifetimes are discussed.
