We studied the scattering process of helium molecules transmitting through vertically aligned single-walled carbon nanotube (VA-SWNT) arrays using the molecular beam technique. The time-of-flight distributions were measured in order to calculate the intensity and energy of scattered molecules. Almost all scattered molecules diffusely reflected or transmitted from the surface after they interacted with VA-SWNT arrays, while few molecules transmitted axially with no interaction. It indicates that incident molecules to as-grown VA-SWNT arrays interacted with SWNT bundles, not substrate. In addition, the intensity of axially transmitted molecules strongly depends on the incident angle, due to the high orientation of SWNT bundles.
