    "abstract": "A number of atomic beam experiments, related to the Ramsey experiment and a\nrecent experiment by Brune et al., are studied with respect to the question of\ncomplementarity. Three different procedures for obtaining information on the\nstate of the incoming atom are compared. Positive operator-valued measures are\nexplicitly calculated. It is demonstrated that, in principle, it is possible to\nchoose the experimental arrangement so as to admit an interpretation as a joint\nnon-ideal measurement yielding interference and ``which-way\u0027\u0027 information.\nComparison of the different measurements gives insight into the question of\nwhich information is provided by a (generalized) quantum mechanical\nmeasurement. For this purpose the subspaces of Hilbert-Schmidt space, spanned\nby the operators of the POVM, are determined for different measurement\narrangements and different values of the parameters.",
