我们报道了一种新的光学技术，它使用光力和飞行时间光谱仪来绝对测量团簇的极化率。这也是第一个准确测量气相中可凝聚团簇交流极化率的报告。我们测定了C-60在1.064微米激光基波长处的光学极化率为α=79+/-4埃。(C)2000年美国物理研究所。[S0021-9606(00)01038-2]。
We report on a new optical technique that uses light forces and a time-of-flight spectrometer to make absolute measurements of cluster polarizabilities. This is also the first accurate report of an ac polarizability measurement of a condensable cluster in the gas phase. We have determined the optical polarizability of C-60 at the fundamental wavelength of a Nd:YAG laser (1.064 mu m) to be alpha=79 +/- 4 Angstrom(3). (C) 2000 American Institute of Physics.
