Atomic Transition Probabilities: Ultraviolet Multiplets of Zn i,ii and Cd i,ii*

Radiative lifetimes for eleven transitions in Zn i,ii and Cd i,ii have been measured by use of a phase-shift method. Lifetimes ranging from 1.75 nsec for the Zn i (4s¹S⁰–4p¹P₀) multiplet to 460 nsec for the Cd ii ( $5p^2{P_{\frac{1}{2}}}^0-4d^{9}5s^2\hspace{0.17em}{{{}^{2}D}_{\frac{3}{2}}}^0$) level were found. These results are compared with previously available data.
