Neon - Spectral Data for the Chandra X-ray Observatory

• Ne V   (Neon   Z = 10)

  C I isoelectronic sequence

  Ground state   1s²2s²2p^{2 3}P₀

  Ionization energy 1 018 000 cm^-1 (126.22 eV)

  Data are tabulated for 106 transitions in the range of 109 Å to 169 Å. Transition probabilities for the 2s²2p²-2s²2p3s and 2s²2p²-2s²2p3d arrays are mean values from MCHF [1] and CIV3 [2] calculations. Remaining results are from the Opacity Project (OP) [3]. The multiplet values from OP have been decomposed into fine-structure components assuming LS-coupling, as indicated by the notation LS in the reference column.

• Ne VI   (Neon   Z = 10)

  B I isoelectronic sequence

  Ground state   1s²2s²2p ²P°_1/2

  Ionization energy 1 273 800 cm^-1 (157.93 eV)

  Data are tabulated for 238 transitions in the range 86 Å to 171 Å. Transition probabilities for the 2s²2p-2s²3s, 2s²2p-2s²3d, and 2s2p²-2s2p3s arrays are taken from MCHF calculations [1]. Remaining results are taken from the Opacity Project (OP) [2]. The multiplet values from OP have been decomposed into fine-structure components assuming LS-coupling, as indicated by the notation LS in the reference column.

• Ne VII   (Neon   Z = 10)

  Be I isoelectronic sequence

  Ground state   1s²2s^{2 1}S₀

  Ionization energy 1 671 792 cm^-1 (207.28 eV)

  Data are tabulated for 132 transitions in the range 65 Å to 160 Å. Transition probabilities for the 2s²-2s3p, 2s2p-2s3s, 2s2p-2s3d, and 2p²-2s3p arrays are taken from MCHF calculations [1]. Values for the 2s²-2p3s, 2s²-2p3d, 2s2p-2p3p, 2p²-2p3s, and 2p²-2p3d arrays were obtained with many-body perturbation theory (MBPT) [2] calculations. Remaining results are taken from the Opacity Project(OP) [3]. The multiplet values from OP have been decomposed into fine-structure components assuming LS-coupling, as indicated by the notation LS in the reference column.

• Ne VIII   (Neon   Z = 10)

  Li I isoelectronic sequence

  Ground state   1s²2s ²S_1/2

  Ionization energy 1 928 462 cm^-1 (239.10 eV)

  Data are tabulated for 58 transitions in the range 55 Å to 172 Å. Most of transition probabilities are taken from the Opacity Project(OP) [1]. Transition probabilities for the 2p ²P^°_3/2-3s ²S_1/2 and 2p ²P^o_1/2-3s ²S_1/2 transitions are taken from calculations with many-body perturbation theory (MBPT) [2]. The multiplet values from OP have been decomposed into fine-structure components assuming LS-coupling, as indicated by the notation LS in the reference column.
