摘要：

We study electron emission from atoms and molecules in collisions with fast electrons and heavy ions (C6+). The soft collision electrons (SE), two center electron emission (TCEE), the binary encounter (BE) events and the KILL Auger lines along with the elastically scattered peaks (in electron collisions) are studied using a hemispherical electrostatic electron analyzer. The details of the measurements along with description of the spectrometer and data acquisition system are given. The angular distributions of the low energy (few eV) electrons in soft collisions and the binary encounter electrons at keV energies are compared with quantum mechanical models based on the first Born (B1) and the continuum distorted wave-Eikonal initial state approximation (CDW-EIS).
