Theoretical study of the C- 4S3/2o and 2D3/2,5/2o bound states and C ground configuration: Fine and hyperfine structures, isotope shifts, and transition probabilities

This work is an ab initio study of the 2p(3) S-4(3/2)o, and D-2(3/2,5/2)o states of C- and 2p(2) P-3(0,1,2), D-1(2), and S-1(0) states of neutral carbon. We use the multiconfiguration Hartree-Fock approach, focusing on the accuracy of the wave function itself. We obtain all C- detachment thresholds, including correlation effects to about 0.5%. Isotope shifts and hyperfine structures are calculated. The achieved accuracy of the latter is of the order of 0.1 MHz. Intraconfiguration transition probabilities are also estimated.
