Angle- and energy-dependent cross sections for electron emission were measured for 68-MeV/u Kr{sup 33+} ions impacting on H{sub 2}. These results show, in accordance with our earlier observation, that interference effects are produced by the coherent emission of electrons from the two H atoms, in analogy with Young's two-slit experiment. Furthermore, the present results demonstrate that the observed oscillatory pattern varies with the electron observation angle, contrary to our earlier expectations but in agreement with recent theoretical predictions.
