Giant enhancement in low energy photoemission of ar confined in C60.
Considering an Ar atom endohedrally sequestered in C60, a phenomenal increase in the photoionization cross section of the confined atom through the dominant outer 3p channel is predicted. The effect occurs owing to a powerful dynamical coherent interchannel coupling between the atomic and the cage ionization channels which redirects the bulk of oscillator strength from the giant surface plasmon to the atomic ionization.
