Atomic properties involving the low-lying excited {sup 2}D{sub 3/2,5/2} states in alkaline-earth-metal ions are of current interest in many different applications ranging from tests of physics beyond the standard model to astrophysics. We have used the relativistic coupled-cluster theory to perform accurate calculations of the lifetimes of the lowest excited {sup 2}D{sub 3/2} and {sup 2}D{sub 5/2} states in singly ionized calcium, strontium, and barium. The importance of electron correlation in these calculations is emphasized. Our results are compared with the available experimental and theoretical data.
