The experiment is conducted in the laser-induced plasma—the Nd:YAG laser, operating at 532 nm, was used to produce plasma from the copper sample in the residual air atmosphere at a pressure of 8 Pa. The electron temperature and density were estimated by the Boltzmann-plot method and from the Saha equation. The investigated Cu I lines belong to the 4s–4p', 4s<sup> 2</sup>–4p'' and 4p'–4d' transitions while Cu II spectral lines belong to the 4s–4p, 4p–5s, 4p–4d, 4p–4s<sup> 2</sup>, 4d–4f and 4d–v transitions. Comparison with existing experimental data was possible only in the case of 17 Cu II lines due to a lack of experimental and theoretical values. The rest of the data, Stark widths of 22 Cu I and 83 Cu II lines are published for the first time.</p> 2013-09-05 00:00:00 electron 17 Cu II lines Cu II Stark widths 83 Cu II lines Atomic Physics Molecular Physics
