A team led by scientists from the University of Washington and the University of Notre Dame used recent advances in electron microscopy to observe Fano interferences directly in a pair of metallic nanoparticles. Fano interference means that electrons in atoms move through two types of energy transitions, one discrete and the other continuous, which result in destructive interference through their synchronized mixing.
