【 摘 要 】

Transmission of low-energy electrons of 200 eV through a single glass capillary was investigated. The results show transmission of electrons at large tilt angles, where direct transmission should be geometrically prevented, thus indicating the existence of the guiding effect. Nevertheless, the transmitted current intensity was found to vary in time, while beside the dominant elastic peak, a significant contribution of inelasticlly scattered electrons was also obtained.
