title: Relativistic coupled-cluster calculations of parity nonconservation in Ba+ by the sum-over-states approach.
abstract: The authors present the results of their calculation for the parity nonconserving 5p(6)6s(1/2)-->5p(6)5d(3/2) transition in Ba+ 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(6)6p(1/2)> state. Their results are in reasonable agreement with other calculations.
