“…The behavior of the rotational populations for CO between 25 and 50 eV arises from the 4 →k shape resonance, which has been observed in previous photoionization studies. 68,88,89 However, these new data enable us to study the shape resonant dynamics with greater clarity than previously possible. Rotationally resolved studies can be particularly valuable for understanding the microscopic behavior of shape resonances for two reasons.…”

“…In particular, the earlier work also shows that the results are free of artifacts such as valence-electron cascades that might complicate the interpretation of the data. 31 The approach of using dispersed fluorescence detection for studies requiring broad spectral coverage has been described in many related contexts, including studies of Franck-Condon breakdown in shape resonant ionization of diatomics, 65,68 triatomics, 66,67,69 and polyatomics. 70 The strategy employed in those studies-probing the ionic vibrational degrees of freedom to elucidate the scattering dynamics-is closely related to the present rotationally resolved studies.…”

“…The N 2 curves show strong deviations from Franck-Condon behavior over a broad range at high energies while the CO results do not. In contrast, the CO results show strong deviations at lower energy, 22,23 while the N 2 curves are relatively flat in this region.…”

“…The fluorescence spectra compared well with those obtained previously over a more limited range. 23 The theoretical methods employed in these studies have been discussed previously 5,6 and only a brief discussion is given here. The photoelectron orbitals are obtained using a procedure based on the Schwinger variational principle.…”
