摘要
Ar^+的自发辐射系数(爱因斯坦 A 系数)在强光场下会发生改变,其改变量与跃迁过程中离子轨道角动量量子数的改变△L 及总角动量量子数的改变△J 相关.
Experimental results show that spontaneous emission coeffi- cients of argon ion Ar^+ vary in instense light field.They are not constant parameters that do not depend on outside conditions.It is also found that their variance is related to change of total angular momentum ΔJ and or- bital angular momentum ΔL of ion during transition.
