Resonance positions and widths are obtained for the low- lying Feshbach resonances in the system. Plots of resonance curves suggest that low- energy dissociative recombination can occur via resonances of (1)Pi, (1)Delta, (3)Sigma(+) and 3 Pi symmetries. Electron impact electronic excitation is considered both for excitation to the first excited A (2)Pi state and to yield a dissociation cross section. The latter calculations suggest that the lower of two experimental measurements of this process is likely to be correct. Finally results are presented for bound states in the continuum for both (1)Sigma- and (3)Sigma(-) symmetries. date: 2007-06-14 publisher: IOP PUBLISHING LTD vfaculties: VMPS oa_status: green primo: open primo_central: open_green article_type_text: Article verified: verified_batch elements_source: Web of Science elements_id: 140829 doi: 10.1088/0953-4075/40/11/015 lyricists_name: Tennyson, Jonathan lyricists_id: JTENN43 full_text_status: public publication: J PHYS B-AT MOL OPT volume: 40 number: 11 pagerange: 2135 - 2145 refereed: TRUE issn: 0953-4075 citation: Chakrabarti, K; Tennyson, J; (2007) R-matrix calculation of the continuum states of carbon monoxide.
