Abstract We investigate angular distributions of the transmitted 60keV and 120keV O3+ ions through nanocapillaries with 50nm diameter and 10μm length. The experimental results are in agreement with the `guiding effect' found by Stolterfoht et al. For different tilted angles of the nanocapillary membrane with respect to the beam, the angular distributions of the transmitted ions are measured by a one-dimensional micro-channel plate (MCP) detector. Moreover, the dependence of this guiding effect on the projectile energy is studied.
