Resonance-Fluorescence Studies. I.Sc45,Ga69, andGa71

Resonant scattering of bremsstrahlung was used to measure $\frac{g\overline{W}{\Gamma }_0{\Gamma }_0}{\Gamma }$ for 13 transitions in ${}_{}{}^{45}{}_{}{}^{}\mathrm{Sc}$ and 18 transitions in ${}_{}{}^{69,71}{}_{}{}^{}\mathrm{Ga}$ below 2.5 MeV. New level widths were measured by direct comparison of resonant scattering from levels of known width. Where branching ratios are known, radiative widths to the ground state ${\Gamma }_0$ are deduced. Comparisons are made between level widths measured in this work and in other measurements. The transition strengths in ${}_{}{}^{69}{}_{}{}^{}\mathrm{Ga}$ are compared with the most recent nuclear model.
