Abstract

Lifetimes of 13 upper states of optical-resonance transitions in selected metal atoms have been measured using the phase-shift method. Data were taken over a range of at least 12 of fluorescence intensity, to take into account the effects of radiation entrapment and exciting light scattering. The following results were obtained: Na 3p ²P⁰ 16.2 nsec, Tl $7s\hspace{0.17em}²S_{\frac{1}{2}}$ 7.65 nsec, Tl $6d²D_{\frac{3}{2}}$ 6.9 nsec, In $6s\hspace{0.17em}²S_{\frac{1}{2}}$ 7.5 nsec, In $5d\hspace{0.17em}²D_{\frac{3}{2}}$ 7.9 nsec, In $5d\hspace{0.17em}²D_{\frac{5}{2}}$ 7.9 nsec, Ga $5s\hspace{0.17em}²S_{\frac{1}{2}}$ 7.6 nsec, Ga 4d ²D 7.7 nsec, Cu 4p ²P⁰ 7.2 nsec, Ag $5p\hspace{0.17em}²P_{\frac{1}{2}}^0$ 6.7 nsec, Ag $5p\hspace{0.17em}²P_{\frac{1}{2}}^0$ 7.5 nsec, Pb 7s ³P₁⁰ 6.05 nsec, and Bi $7s\hspace{0.17em}⁴P_{\frac{1}{2}}$ 5.9 nsec. Estimated absolute accuracies vary between 3 and 7%.
