The (2s1/22p1/222p3/22)5/2-(2s22p1/222p3/2)3/2 x-ray transition in the N-like 208Pb75+was observed using the Tokyo electron beam ion trap at the University of Electro-Communications. The Pb spectral line energies were measured relative to the Lyman-a lines of the H-like S and the 1s4p 1P1-1s2 1S0 transition in the He-like P. In the present work, the line from the N-like lead ions is analysed and the transition energy is determined to be 2662.98 +- 0.12 eV. We also calculate the transition energies of the (2s1/22p1/222p3/22)5/2-(2s22p1/222p3/2)3/2 lines in N-like ions from Sn (Z = 50) through U (Z = 92) with the general relativistic atomic structure package Vanderbilt University (GRASPVU) package which is based on the multiconfiguration Dirac-Fock (MCDF) method. The calculations are compared with the available experimental results. [ABSTRACT FROM AUTHOR]
