Electron interference patterns have been obtained by using an iron whisker as the electrostatic fiber of a Mo¨llenstedt [G. Mo¨llenstedt and H. Du¨ker, Z. Physik145, 377 (1956)] interferometer. The tilted fringes in the shadow pattern resemble those observed by Chambers [R. G. Chambers, Phys. Rev. Letters5, 3 (1960)] and show the relationship between flux leakage and geometrical shape of the whisker. Chambers' general model of the flux configuration is confirmed.
