Title: Measurement of the lifetimes of the lowest {sup 3}P{sub 1} state of neutral Ba and Ra

Abstract

The lifetimes of the lowest {sup 3}P{sub 1} states of Ba and Ra were determined to be 1345{+-}14 ns and 422{+-}20 ns, respectively, by measuring the exponential decay of fluorescence after illuminating a thermal atomic beam with pulses of laser light. In addition, the {sup 1}S{sub 0}(F=1/2)-{sup 3}P{sub 1}(F=3/2) transition frequency in {sup 225}Ra was measured to be 13 999.269{+-}0.001 cm{sup -1} by referencing a nearby I{sub 2} transition.
