【 摘 要 】

The transmission of electrons through a tapered glass capillary was observed for 1000 eV incident electrons up to tilt angles of ∼9.5°. Tilt angle dependence of the energy loss broadening shows clear correspondence of elastic and inelastic processes. Both were found for smaller tilt angles.
