Electron biprism technique, if extended to any charged particles, will make comparison possible among two-beam interference fringes of electrons and other particles under the same(including wave length)geometrical condition. Combination of the technique with sharply focusing mass spectroscopy will realize such experiments. Due to the tradition since Young-Fresnel, it is believed that two-beam visibilities of particles of various masses under the same geometrical setup are constant and independent of each total sum of macroscopically separated path-lengths, which is not to be confused with ordinary path-difference.(See Fig. 2.)But the assumption of such constant visibility has never been verified experimentally and seems to become gradually unnatural as the masses increase. Experimental reexamination of the assumption is proposed with method of observing an expected mass effect on interdependence between visibility and pathlengths. The smaller visibilities are expected for the heavier masses and the longer path-lengths, contrary to conventional constant visibility; e.g., ≅0.4 for protons of wave length 0.02Å and beam width0.2μ in a realizable experimental setup. Technical problems for the experiment and effects to the observation theory are discussed.
