A three-dimensional trap for Rydberg atoms in selected Stark states has been realized experimentally. H atoms seeded in a supersonic expansion of Ar are excited to the low-field seeking n=30, k=25, |m|=0, 2 Rydberg-Stark states, decelerated from a mean initial velocity of 665 m/s to zero velocity in the laboratory frame and loaded into a three-dimensional electrostatic trap. The motion of the cold Rydberg atom cloud in the trap and the decay of the trapped atoms have been studied by pulsed electric field ionization and imaging techniques.
已通过实验实现了一种用于处于特定斯塔克态的里德堡原子的三维阱。在氩气的超声速膨胀中注入的氢原子被激发到低场寻的(n = 30)，(k = 25)，(|m| = 0)，(2)的里德堡 - 斯塔克态，在实验室坐标系中从平均初始速度(665)米/秒减速到零速度，并被加载到一个三维静电阱中。通过脉冲电场电离和成像技术研究了冷里德堡原子云在阱中的运动以及被捕获原子的衰变。
