Phys. Rev. Lett. 87, 023201 (2001) [4 pages]Evidence for Interference Effects in Electron Emission from H2 Colliding with 60MeV/u Kr34+ IonsReceived 17 January 2001; revised 3 April 2001; published 21 June 2001 Cross sections for electron emission in the energy range from 2–300eV were measured for 60MeV/u Kr34+ ions impacting on H2. 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 250eV in good agreement with the calculations. The oscillatory structure is found to be similar for the observation angles 20°, 30°, 150°, and 160°. © 2001 The American Physical Society URL:
