摘要:

高度极化的亚稳态He ~*($\mathrm{2^3S}$)和Ne ~*($\mathrm{2^3P}$)原子已从100 nm周期的氮化硅透射光栅中衍射,并从衍射强度到第10级确定了激发原子与氮化硅表面相互作用的范德华系数$C_3$。计算结果与基于非延迟Lifshitz公式的计算结果一致。

英文摘要:

Highly polarizable metastable He* ($\mathrm{2^3S}$) and Ne* ($\mathrm{2^3P}$) atoms have been diffracted from a 100 nm period silicon nitride transmission grating and the van der Waals coefficients $C_3$ for the interaction of the excited atoms with the silicon nitride surface have been determined from the diffraction intensities out to the 10th order. The results agree with calculations based on the non-retarded Lifshitz formula.
