摘要：
Cross sections for electron emission in the energy range from 2-300 eV were measured for 60 MeV/u Kr34+ ions impacting on H-2. Model calculations are introduced to guide the search for interference effects in the electron spectra produced by the coherent emission of electrons from the two H atoms in analogy with Young's two-slit experiment. Experimentally, a full sinusoidal-like oscillation was observed in the energy range up to 250 eV in good agreement with the calculations. The oscillatory structure is found to be similar for the observation angles 20 degrees, 30 degrees, 150 degrees, and 160 degrees.
