摘要:

由激光冷却原子组装含银(Ag)的超冷极性分子,需要了解银在方便激光波长下的动态极化率。我们给出了中性银低激发态能量以及电偶极直流和交流极化率的计算与分析。对4d^{10}x态(其中x=5s、6s、7s、5p、6p、7p、5d、6d和4f)的性质计算采用线性化耦合簇单双激发方法。4d^9 5s^2 ^2D_{5/2,3/2}态的性质则在价态场中分别以11个和17个电子进行组态相互作用计算得到。我们分析了极化率的不同贡献,并估计了预测结果的不确定度。

英文摘要:

Assembly of ultracold polar molecules containing silver (Ag) from laser-cooled atoms requires knowledge of the dynamic polarizabilities of Ag at convenient laser wavelengths. We present calculations and analysis of the energies and electric-dipole dc and ac polarizabilities of the low-lying states of neutral Ag. Calculations of the properties of the 4d^{10}x states, where x=5s,6s,7s,5p,6p,7p,5d,6d, and 4f, are performed using the linearized coupled cluster single-double method. The properties of the 4d^9 5s^2 ^2D_{5/2,3/2} states are obtained within the framework of configuration interaction with 11 and 17 electrons in the valence field. We analyze the different contributions to the polarizabilities and estimate the uncertainties of our predictions.
