We investigate the interactions of 50-2500 eV electrons with vapor deposited ice by means of Electron Energy Loss Spectroscopy (EELS), Auger Electron Spectroscopy (AES), and Secondary Electron Emission (SEE). The EELS data is used to measure low lying excitations and to ascertain the production of radicals in the near surface region. This is done by observing the appearance of energy loss features in the band gap region as a function of irradiation fluence. We will discuss electrostatic charging and chemical alterations during irradiation and relate the results to astronomical problems.
