The authors present the results of their calculation for the parity nonconserving 5p{sup 6}6s{sub 1/2}{yields}5p{sup 6}5d{sub 3/2} transition in Ba{sup +} using the relativistic coupled-cluster theory in the singles, doubles, and partial triples approximation. The contributions from the leading intermediate states are explicitly considered. It is found that the largest contribution comes from the |5p{sup 6}6p{sub 1/2}> state. Their results are in reasonable agreement with other calculations.
