    "abstract": "In an analysis of the Afshar experiment R.E. Kastner points out that the\nselection system used in this experiment randomly separates the photons that go\nto the detectors, and therefore no which-way information is obtained. In this\npaper we present a modified but equivalent version of the Afshar experiment\nthat does not contain a selection device. The double-slit is replaced by two\nseparate coherent laser beams that overlap under a small angle. At the\nintersection of the beams an interference pattern can be inferred in a\nnon-perturbative manner, which confirms the existence of a superposition state.\nIn the far field the beams separate without the use of a lens system. Momentum\nconservation warranties that which-way information is preserved. We also\npropose an alternative sequence of Stern-Gerlach devices that represents a\nclose analogue to the Afshar experimental set up.",
