The B-spline R-matrix method is used to investigate the electron-impact excitation of neutral carbon an in the low-energy near-threshold regions. The excitation cross sections exhibit prominent resonance structures in these energy region, especially for the weak spin-forbidden transitions and transitions from metastable states. The energy positions, widths, and classifications for the detected resonances are presented.References
