Shape resonance phenomena in CO following K-shell photoexcitation

Journal Article · · Phys. Rev. Lett.; (United States)
Electron cross sections and asymmetries following photoexcitation of the CO K shells were measured directly. Energy analysis of ejected electrons yielded cross sections exhibiting sigma shape resonances in the C(1s), C(KVV), and O(1s) channels, and a ..pi.. resonance in the C(KVV) channel, confirming earlier indirect measurements. Asymmetry measurements showed a sigma shape resonance in the C(1s) channel, in good agreement with the predictions of Dehmer and Dill. The C(KVV) ..pi.. resonance showed nearly isotropic behavior.
