Absolute oscillator strengths are computed by the STF method for selected lines of Scl.The lifetimes deduced from these values are in satisfactory agreement with recent beam-foil measurements. From a study of 10 selected lines, a new value of the solar photospheric abundance is derived (logNsc = 3.04) in agreement with the meteoritic value.

Oscillator strengths are calculated for 259 lines of Ti I by taking configuration interaction into account in a somewhat simplified treatment. Radial integrals are obtained by an adaptation of the scaled Thomas-Fermi method. The great majority of selected lines originate from slightly perturbed terms. From a satisfactory comparison of our gf-values with recent experimental data and with solar results in the visible region, we have been able to extend the work for some infrared lines. Very few transition probabilities were known for Ti I in that spectral range.On the basis of our oscillator strengths, a mean value logNTi = 4.88 -4-0.12 (in the usual scale), is proposed for the solar photospheric abundance, in agreement with the meteoritic value.

Oscillator strengths calculated by the STF method for selected transitions of V I and Co I have permitted to deduce, from an LTE study of weak lines, photospheric abundances in agreement with those obtained from carbonaceous chondrites. A summary of results is also presented for all the iron-group elements.
