Abstract :
Coherence of inelastically scattered electrons was investigated by means of biprism interference experiments performed in a transmission electron microscope equipped with a highly coherent field emission gun and an imaging filter. The experimental results show that within the wave inelastically scattered at aluminium plasmons there is in fact an area of about 10 nm diameter with coherence sufficient to take electron holograms.
