    "abstract": "For a quantum-mechanically spread-out particle we investigate a method for\ndetermining its arrival time at a specific location. The procedure is based on\nthe emission of a first photon from a two-level system moving into a\nlaser-illuminated region. The resulting temporal distribution is explicitly\ncalculated for the one-dimensional case and compared with axiomatically\nproposed expressions. As a main result we show that by means of a deconvolution\none obtains the well known quantum mechanical probability flux of the particle\nat the location as a limiting distribution.",
