Abstract: | Oscillator strengths for the singlet 3sns(1S)-3smp(1P); (n, m = 3-7), 3snp(1P)-3smd(1D); (n = 4-7, m = 3-6) and the triplet 3sns(3S)-3smp(3P); (n = 4-7, m = 3-7), 3snp(3P)-3smd(3D); (n = 4-7, m = 3-6) transitions in the Mg I sequence are calculated in LS-coupling scheme. The Coulomb approximation is used in calculating the radial part of the wave functions, while the angular part is determined using the Racah technique. Lifetimes of the upper 3sns(3S, 1S); (n = 4-7) and 3snp(3P, 1P); (n = 3-7) excited states are obtained and compared with the available experimental data. |
