We investigate the angular distribution of the transmitted 18keV negative ions Cl through Al 2 O 3 nanocapillaries of 50 nm in diameter and 10 μm in length.Elastic scattering ions and inelastic scattering ions are obtained simultaneously.The experimental result is partially consistent with the guiding effect.We can qualitatively explain our experimental result through a dynamic process.
