    "abstract": "In the context of the quantum mechanical modelling of a measurement process\nusing the Stern-Gerlach setup, we critically examine the relationship between\nthe notion of `distinguishability\u0027 of apparatus states defined in terms of the\ninner product and spatial separation among the emerging wave packets. We show\nthat, in general, the mutual orthogonality of these wave packets does not\nnecessarily imply their unambiguous spatial separation even in the asymptotic\nlimit. A testable scheme is formulated to quantify such departures from\n`idealness\u0027 for a range of relevant parameters.",
