All Tables
- Table 1:
Energy levels of O V. Energies are taken from Wiese et al. (1996). Levels 2-4 are the metastable levels discussed in this
paper.
- Table 2:
Strongest X-ray lines of O V. The values listed apply for
the full multiplets (not splitted into sublevels).
- Table 3:
Core-excited energy levels in O V. Columns (1) and (2):
configuration and term; Cols. (3) and (4): calculated energy of the Auger electron
for a transition to the 1s2 2s 2S (ground) state of
O VI where only transition energies to the 1s2 2p 2P state are
given in the original reference these have been corrected for the energy
difference between the 2S and 2P state; Col. (5): measured ;
Col. (6): adopted ;
Col. (7): adopted energy
of the
level.
- Table 4:
Wavelength comparison of the X-ray lines of O V.
Wavelengths are given in Å. The column "Cowan'' gives
from
Table 2; "corr.'' are these calculated wavelengths corrected
as described in the text; "Auger'' are the wavelengths determined from
Auger energies as listed in Table 3; "CC'' are the calculations
by Chen & Crasemann (1987); "HULLAC'' are the wavelengths
calculated using the HULLAC code.
- Table 5:
Oscillator strengths f, total transition
probabilities
,
Auger decay rates
and total
transition rates
of O V. Transition probabilities
are in units of 1012 s-1.
- Table 6:
Observed absorption lines in Mrk 279, due to or related to O V.
The observed wavelength
is given with two error bars: the first is
the statistical uncertainty, the second the systematic due to the wavelength
calibration uncertainty of the LETGS. For lines with wavelength fixed, the
observed equivalent width (EW) is merely the formal upper limit. The line
around 22.50 Å is either fitted by a single line (22.540 Å) or
alternatively by two lines (22.501 and 22.548 Å).
- Table 7:
Densities (in m-3) for 2s 2p triplet to ground ratio's of 0.125,
0.5 and 2, for a total O V column density of
m-2.
