In this paper, we report calculated values of the Stark widths and shifts for 72 spectral lines of Pb v . They were calculated using the Griem semi‐empirical approach. A set of wavefunctions obtained from Hartree–Fock relativistic calculations including core polarization effects was used. Stark widths and shifts corresponding to lines arising from 5d 9 n s ( n = 7, 8), 5d 9 6p, 5d 9 6d and 5d 9 5f configurations of Pb v . Stark widths and shifts are presented for an electron density of 10 17 cm −3 and temperatures T = 1.6–5.0 (10 4 K). The 2142.5, 2167.9 and 2278.6 Å lines of Pb v recently measured are included in our calculations. In this case, we have included for comparison calculations without core polarization effects. There is good agreement between our calculations and the above‐cited experimental values.
