| 摘 要： | 用偏振激光两步激发,获得不同│ml│值的里德伯态,在2.4kV/cm以下的电场范围内,测定了Sr原子5snd(n=22-27),│ml│=0,1,2各里德伯态的电离阈值。理论给出了二阶近似下│ml│有关的电离阈,并与测量结果作了对照。

| Abstract: | We have obtained Rydberg atom of different |ml| value by two-step excitation using polarized lasers. The field-ionization thresholds for 5snd (n= 22-27), | ml| =0,1,2 Rydberg states of Sr atom is measured by using a pulse electric field (up to 2.4kV/cm). Second-order approximate formula of field-ionization threshold that depend on the |ml| value is obtained and compared with the measured data. |
