Photoelectron spectrum of neon

FIGURE 5.19 Photoelectron spectrum of neon. The spectrum shows three peaks, demonstrating that the electrons of neon are organized in three bonding states of distinct energy values. The peak at 383.4 eV has been reduced by a factor of 4 for display on the same scale as the other two.

Then the initial excited state l 2 (2p 3d ( S) P) can be reached from the ground state via two paths (see Fig. 14), either via the admixture of 3d ( S) in the ground state or via the admixture of 2p54s2 in the excited state. (This is exactly the same mechanism of excitation as discussed in connection with the Is photoelectron spectrum of neon ). A MCHF calculation of the two configurations 4s and 3d2(ls) mixed into the ground state (see (5a)) or into the or inner-vacancy state functions...
