We present a collision-induced light scattering spectrum of Ne(2) and analyze it, together with an induced spectrum of Ar(2), in terms of a model for the pair-polarizability anisotropy beta of an atomic gas. This model, which is in essence a slight modification of one introduced by Ceccherini et al. [J. Chem. Phys. 111, 6316 (1999)], is shown to describe the measured spectra much farther into the wings than does the original model. The agreement of our measurements with quantum-mechanical spectra from the most reliable, now available, ab initio computation methods for beta produces evidence in support of the data and counters criticism of our experiment.
我们展示了Ne₂的碰撞诱导光散射光谱,并根据原子气体对极化率各向异性β的模型对其以及Ar₂的诱导光谱进行了分析。该模型本质上是对Ceccherini等人[《化学物理杂志》111, 6316 (1999)]所引入模型的轻微修改,结果表明,与原始模型相比,该模型能够更深入地描述测量光谱的边缘部分。我们的测量结果与目前最可靠的从头计算方法得出的β的量子力学光谱相符,这为数据提供了支持,并反驳了对我们实验的批评。
