摘　　要：里德堡原子具有正比于主量子数n3超长寿命的特点,可以反映出里德堡原子的能级信息及其特殊的原子结构。基于Marinescu提出的单电子模型势,采用数值积分计算出Na原子高n里德堡态的径向矩阵元,进而计算出Na原子在不同温度下高n里德堡态的辐射寿命。Rydberg atom has the characteristic of super long life proportional to the principal quantum number n3,so it can reflect the energy level information of Rydberg atom and its special atomic structure.Based on the single-electron model potential proposed by Marinescu,the radial matrix element of high n Rydberg state of Na atom is calculated by numerical integration,and then the radiation lifetime of high n Rydberg state of Na atom at different temperatures is calculated.

关 键 词：里德堡原子 辐射寿命 碱金属原子
