    "abstract": "The dynamics of a quantum system undergoing frequent \"measurements\", leading\nto the so-called quantum Zeno effect, is examined on the basis of a\nneutron-spin experiment recently proposed for its demonstration. When the\nspatial degrees of freedom are duely taken into account, neutron-reflection\neffects become very important and may lead to an evolution which is totally\ndifferent from the ideal case.",
