    "abstract": "We demonstrate the existence of new nonclassical correlations in the\nradiation of two atoms, which are coherently driven by a continuous laser\nsource. The photon-photon-correlations of the fluorescence light show a spatial\ninterferene pattern not present in a classical treatment. A feature of the new\nphenomenon is, that bunched and antibunched light is emitted in different\nspatial directions. The calculations are performed analytically. It is pointed\nout, that the correlations are induced by state reduction due to the\nmeasurement process when the detection of the photons does not distinguish\nbetween the atoms. It is interesting to note, that the phenomena show up even\nwithout any interatomic interaction.",
