Upon electron bombardment, some elements, such as P, show an electron energy loss profile with a peak at a specific energy loss value. By collecting a series of images of a field at different energy l...

Phosphorus has a characteristic electron energy loss with an edge at 160 eV. The Zeiss 902 electron microscope permits images to be recorded at different energy losses which can be digitized and proce...
