Transition probabilities of lines related to odd terms based on the lowest (5D) parent of Fe II have been calculated using the orthogonal operator approach for both the odd and the even energy levels. The obtained log(gf) values are used to calculate the solar Fe-abundance. The result, AFe = 7.59 [FORMULA] 0.06, is the average of the two abundance values proposed in recent literature.
