Abstract: Investigation of the field-induced desorption of cesium atoms from the surface of rhenium crystal emitter carbon-saturated in benzene vapors showed that, after desorption from the surface, the process continues and there appears a contour of desorption around $\{10\bar11\}$ and $\{1\bar100\}$ faces that contracts toward the centers of faces with increasing field strength. This previously unreported anomalous behavior of the field-induced desorption is explained by the intercalation of cesium into graphite structures formed on the emitter surface.
