Direct observation of Young's double-slit interferences in vibrationally resolved photoionization of diatomic molecules.
(2011) In Proceedings of the National Academy of Sciences 108(18). p.7302-7306- Abstract
- Vibrationally resolved valence-shell photoionization spectra of H(2), N(2) and CO have been measured in the photon energy range 20-300 eV using third-generation synchrotron radiation. Young's double-slit interferences lead to oscillations in the corresponding vibrational ratios, showing that the molecules behave as two-center electron-wave emitters and that the associated interferences leave their trace in the angle-integrated photoionization cross section. In contrast to previous work, the oscillations are directly observable in the experiment, thereby removing any possible ambiguity related to the introduction of external parameters or fitting functions. A straightforward extension of an original idea proposed by Cohen and Fano [Cohen... (More)

Results of accurate theoretical calculations are in excellent agreement with the experimental findings. (Less)
