Abstrakt

We present electric deflection results for the fullerenes C60 and C70 obtained with a long-baseline matter-wave interferometer. The second grating of the interferometer is interchangeable between a material grating for fast atom beams and an optical phase grating for polarizable molecules. This allows us to use cesium as a calibration particle and thus measure molecular susceptibilities with improved systematic uncertainty. The static polarizabilities of C60 and C70 are measured as 4πɛ0×87.4±0.4±2.5Å3 and 4πɛ0×106.4±0.2±1.1Å3, respectively, in excellent agreement with previous deflection experiments, but with improved uncertainties.
