    "abstract": "The formalism allowing one to account for the effect of a finite space-time\nextent of particle production region is given. Its applications to the lifetime\nmeasurement of hadronic atoms produced by a high-energy beam in a thin target,\nas well as to the femtoscopy techniques widely used to measure space-time\ncharacteristics of the production processes, are discussed. Particularly, it is\nfound that the neglect of the finite-size effect on the pionium lifetime\nmeasurement in the experiment DIRAC at CERN could lead to the lifetime\noverestimation comparable with the 10% statistical error. The theoretical\nsystematic errors arising in the calculation of the finite-size effect due to\nthe neglect of non-equal emission times in the pair center-of-mass system, the\nspace-time coherence and the residual charge are shown to be negligible.",
