Parity non-conservation effect; nuclear anapole moment; relativistic coupled-cluster method
We present the results of our calculations of the parity nonconserving electric dipole amplitudes(E1(PNC)) for the 6s(2)S(1/2) - 5d(2)D (3/2;5/2) transitions of Cs-133 employing a relativistic coupled-cluster (RCC) method. E1(PNC) values for the nuclear spin-independent and nuclear spin-dependent (NSD) parity non-conservation (PNC) effects for different hyperfine levels of the 6s(2)S(1/2) - 5d(2)D(3/2) transition and only due to the NSD PNC interaction Hamiltonian for all possible hyperfine levels of the 6s(2)S(1/2) - 5d(2)D(5/2) transition are given. We have also performed calculations of several properties that are relevant for assessing the reliability of the calculations of the amplitudes of the above-mentioned transitions. We highlight the importance of correlation effects by giving the results of both the Dirac-Fock and RCC contributions. Approximate contributions to these properties from the Breit and quantum electrodynamic interactions have also been evaluated. Plausible experimental schemes to measure these transition amplitudes by light shift techniques and interference involving induced Stark shifts are outlined.
