Erratum: “Ring-breaking electron attachment to uracil: Following bond dissociations via evolving resonances” [J. Chem. Phys. 128, 174302 (2008)]

摘要

The elastic cross section for A" e~--uracil scattering presented in the lower panel of Fig. 2 in Ref. 1 was not converged to within 1% as stated in that paper, where the electron-molecule interaction potential was truncated at 10 A from the center of the molecule. In Fig. 1 we show how that cross section changes with increasing truncation distance. We clearly see that increasing the truncation distance leads to a dramatic increase in the A" cross section near threshold. Thus the very low energy peak in the results given in Ref. 1 was not a resonant feature but was an artifact of the small truncation radius used in that work, which suppressed the effects of the dipolar potential of the gas-phase uracil molecule.
