Abstract:We have attempted to extend existing lists of log(gf) values for singly-ionized elements of the iron group introducing systematic corrections to Warner's determinations (Warner, 1967). The suggested corrections shift Warner's-log(gf) system into Kurucz-Peytremann's system. We compare Warner's corrected log(gf) with other modern values; results are quite satisfactory for iron although not as good for titanium, which still shows residuals correlating with the strength of the line. Abundances consistent with those currently accepted are obtained for the iron group in the solar photosphere if our proposed corrected log(gf) values are used.Once systematic corrections to Warner's original values are applied, and after eliminating some individual log(gf) which are probably wrong, the internal consistency of Warner's corrected log(gf) is found to be sgrsime0.20 dex (sgr=standard deviation of a single log(gf)).Research supported in part by the SECYT.
