摘要

角动量j>12j>\frac12的原子态的动态极化率对量子化轴e^z\hat{e}_z与偏振矢量ϵ^\hat{\mathbf{\epsilon}}之间的角度敏感,这源于各向异性张量极化率的贡献。使原子跃迁的微分斯塔克位移为零的魔术波长依赖于该角度。我们确定了在线偏振光情况下,Ca+^{+}离子4s123d32,524s_{\frac12}\to3d_{\frac32,\frac52}跃迁在e^z\hat{e}_zϵ^\hat{\mathbf{\epsilon}}间不同角度下的魔术波长。我们发现,靠近395.79 nm、位于4s124p124s_{\frac12}\to4p_{\frac12}4s124p324s_{\frac12}\to 4p_{\frac32}跃迁波长之间的魔术波长对角度不敏感,而长于3d524p323d_{\frac52}\to 4p_{\frac32}共振跃迁波长(854.21 nm)的魔术波长对角度非常敏感。
