electron ejected from an atom as a result of the interaction of incident radiation with matteran electron ejected from an atom due to the interaction of incident radiation with matter
<microscopy> Produced by an incident electron passing near an atom in the specimen, near enough to impart some of its energy to a lower energy electron (usually in the K-shell). This causes a slight energy loss and path change in the incident electron and the ionisation of the electron in the specimen atom. This ionised electron then leaves t...
