Abstract
The lifetime of the state of atomic radium is determined to be using cold atoms prepared in a magneto-optical trap. The state is populated from the decay of the state which is excited by a pulse of 483 nm light. The decay of the state is observed by detecting delayed fluorescence at 714 nm from the last step in the decay sequence . The measured lifetime is compared to a number of theoretical calculations. An improved value of the level of is obtained.
