Lifetime of the 7s6d {sup 1}D{sub 2} atomic state of radium.
The lifetime of the 7s6d {sup 1}D{sub 2} state of atomic radium is determined to be 385(45) {mu}s using cold {sup 226}Ra atoms prepared in a magneto-optical trap. The {sup 1}D{sub 2} state is populated from the decay of the {sup 1}P{sub 1} state which is excited by a pulse of 483 nm light. The decay of the {sup 1}D{sub 2} state is observed by detecting delayed fluorescence at 714 nm from the last step in the decay sequence {sup 1}P{sub 1}-{sup 1}D{sub 2}-{sup 3}P{sub 1}-{sup 1}S{sub 0}. The measured lifetime is compared to a number of theoretical calculations. An improved value of the 7s7p {sup 1}P{sub 1} level of 20 715.598(6) cm{sup -1} is obtained.
