As examples, several Fano resonances in the extreme ultraviolet photoionization spectrum of neon are attributed to autoionizing states. Some are due to one-electron excitations, such as a series of three strong similarly shaped peaks at energies of 45.546, 47.121 and 47.692 eV which are interpreted as 1s 2s 2p n p (P) states for n = 3, 4 and 5. These states of neutral neon lie beyond the first ionization energy because it takes more energy to excite a 2s electron than to remove a 2p electron. When autoionization occurs, the n p → 2s de-excitation provides the energy needed to remove one 2p electron and form the Ne ground state.
