We present a method for measuring the scalar polarizability of molecules by means of near-field matter-wave interferometry. This technique is applicable to a wide range of complex neutral molecules. A key feature of our experiment is the combination of good transmission and high spatial resolution, gained by imprinting a submicrometer spatial modulation onto a wide molecular beam. Our method significantly improves the measurement sensitivity of the polarizability-dependent shifts. We have successfully performed measurements on fullerenes and report the polarizability to be ?=88.9±0.9±5. 1 3 for C60 and ?=108.5±2.0±6.2 3 for C70. © 2007 The American Physical Society.
