Schnabel, R., Kock, M., Holweger, H.: Selected FeII lifetimes and f-values suitable for a solar abundance study.

A&A; in press (1998)



Abstract:

A selected number of FeII level lifetimes have been measured anew with an improved experimental equipment and evaluation procedure yielding data with uncertainties around 1%. The lifetimes have been used to rescale the corresponding oscillator strength and to derive solar abundances. On average, the iron abundance, log N(Fe) = 7.42 +/- 0.09 on the scale log N(H) = 12, is further reduced supporting the lower abundance results in the literature.
