Abstract: We have used relativistic distorted-wave method to study electron-impact excitation of the fine-structure transitions from the 6s26p2P1/2,3/2 states to the excited 6s26d2D3/2,5/2, 6s6p2 2D3/2,5/2 and 6s27 s2S1/2 states of Pb+ ion. The bound state wavefunctions of the target ion are obtained within the multi-configuration Dirac-Fock approach. The reliability of the calculated wavefunctions is determined by comparing our calculated oscillator strengths for the different transitions with the available measurements and other theoretical calculations. Finally, the cross sections for all the considered fine-structure transitions are reported in the incident electron energy range from the excitation threshold to 100 eV. Cross section results for the resonance transition 6s26p2P1/2 → 6s26d2D3/2 are compared with the only available recent measurements [Gomonai et al. Eur. Phys. J. D 71 31 (2017)] and good agreement is found at the high incident electron energies. © 2019, Springer Nature Singapore Pte Ltd.
