Article Description

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 5dns (n = 7, 8), 5d6p, 5d6d and 5d5f configurations of Pb v. Stark widths and shifts are presented for an electron density of 10cm and temperatures T = 1.6-5.0 (10K). The 2142.5, 2167.9 and 2278.6Å 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. © 2012 The Authors Monthly Notices of the Royal Astronomical Society © 2012 RAS.
