Abstract
The energy spectra of secondary electrons emitted in the wide region o f exit angles delta' (from delta' = 0.8-degrees up to delta' = 90-degr ees) were examined for the cold (40 K) (100) nickel target bombarded w ith 5 keV Ne' ions. The electron energy spectrum shows some structure which strongly shifts to the side of low energy while delta increases. This shift can exceed the work function for the nickel. Such result s uggests that the angular distribution of generated electrons should be anisotropic, and it is possible under assumption that the electron cr eation takes place on the target surface.
