| Abstract: | First experimental evidence for the existence of an electrooptic effect for cold neutrons in 7LiNbO3 is reported and discussed. The effect is based on the fact that in certain photorefractive crystals a light-induced space-charge field can be generated which causes a modulation of the density via the inverse piezoelectric effect. From such density structures, induced by the internal electric field, cold neutrons can be diffracted.
