Precision measurement of relative oscillator strengths for Ti I – II. Transitions from levels ${a}^{5}{F}_{1-4},(0.81-0.84,text{eV}),,{a}^{1}{D}_{2},(0.90,text{eV}),text{and},{a}^{3}{P}_{0-2}$(1.5-1.07 eV)

Relative oscillator strengths are given for 22 lines of Ti I in the range $0.81\,\text{eV}\lt \chi \lt 1.07\,\text{eV},428\,\text{nm}\,\lt \lambda \lt 843\,\text{nm}\,\text{and}+0.50\gt\text{log}\,gf \gt -1.47)$ measured in absorption using the Oxford furnace technique with an accuracy of 0.5 per cent. The relative values have been placed on an absolute scale to an estimated accuracy of 12 per cent by comparison with 0 eV Ti I lines, relative measures of which have previously been placed on an absolute scale using lifetime and atomic beam measurements. Comparisons are made with the data of other experimenters and with theoretical values.
