Abstract
We present the results of secondary-electron cascade calculations of s everal systems and determine the relative yield due to these metal ele ctron cascades depending on the nature of the electron emitting proces s and its energy. We conclude that for slightly charged systems such a s He2+ and Ne2+ the cascade emission can account for 60% of the total electron yield, while it is irrelevant for highly charged species such as Ar12+ when subsurface neutralization is not included.
