Abstract
Measurements of the relative oscillator strengths of 52 lines of Ti I with excitation potential between 1.42 eV and 2.31 eV, made to an accuracy of 1 per cent using the Oxford furnace technique, are reported. The absolute scale for Ti I derived in a previous paper in this series for 0 eV lines, is rediscussed using the additional oscillator strengths for high excitation lines contained in this paper. No change is suggested, and all the relative oscillator strengths are placed on this absolute scale. Comparisons are made with the calculated values of Kurucz and Peytremann, the solar values of Kostyk, and with other experimental results. This paper ends the present study of Ti I lines using the 3-pass system with the Oxford furnace, and comparisons are made between all the 137 Oxford oscillator strengths so far measured and other data. Empirical conversion formulae are given.Keywords
