- Аннотация: We report the experimental Stark widths of Mn I lines belonging to multiplets z(6)P°→a(6)S and z(6)D°→a(6)D in long spark induced by laser. We have used aluminum alloy containing 80 ppm of manganese as a target to avoid strong self-absorption of Mn I lines. Its absence was proved by the comparison of observed intensities with relative strengths of lines within multiplets. Electron density of plasma estimated by Mg I (5172.68 Å) and Al II (2816.18 Å) lines was within the range of (4-30)×10^16 cm-3. The shortest possible gate allowed the observation of symmetric atomic and ionic lines. The spatial profiles of plasma temperature and electron density along the axis of long spark demonstrated that both values were lower than for spherical plasma. Measured Stark widths of resonance multiplet z(6)P°→a(6)S decrease from 0.075 Å for its first component to 0.055 Å for the last one, while Stark widths of components of multiplet z(6)D°→a(6)D increase from 0.095 Å to 0.125 Å. No Stark shifting was observed for the studied multiplets.
