Abstract

The lifetime of the 7s6d D1 2 state of atomic radium is determined to be 385 (45) μs using cold R 226 a atoms prepared in a magneto-optical trap. The D1 2 state is populated from the decay of the P1 1 state which is excited by a pulse of 483 nm light. The decay of the D1 2 state is observed by detecting delayed fluorescence at 714 nm from the last step in the decay sequence P1 1 - D1 2 - P3 1 - S1 0. The measured lifetime is compared to a number of theoretical calculations. An improved value of the 7s7p P1 1 level of 20715.598 (6) cm-1 is obtained.
