Double- and multi-slit interference in photodetachment from nanometer organic molecular anions

We present the predictions of double-slit and multislit interference of photoelectrons from a nanometer-size molecular negative ion. The interference clearly appears in both photoelectron angular distributions and photodetachment cross sections. In contrast to the diatomic photoelectron interference via the X-ray photon, the interference in the nanometer-size negative ions can be readily observed via a visible or extreme ultraviolet laser. Therefore, the phenomenon can be realized on a table-top setup, instead of a large accelerator.
