Photodetachment of the outer shell of C- in the ground state
Résumé
Photodetachment of the outer shells of the ground So4 state of C- using an augmented R -matrix theoretical methodology has been studied from threshold to 13eV . Total and partial cross sections and photoelectron angular distribution asymmetry parameters have been obtained. Excellent agreement between length and velocity formulations is found. The results resolve a discrepancy among earlier calculations, and a new shape resonance, 1s22s22p3s3p P4 , at a photon energy of 8.588eV is predicted.
